If at first you don’t kill enough boneheaded teenagers, try, try again.\n<\/p>\n
I Know What You Did Last Summer<\/a>, out this weekend, is a legacy sequel to the 1997 slasher of the same name. It follows a pair of sequels \u2014 released in 1998 and 2006, respectively \u2014 and an Amazon Prime series<\/a> that was canceled after just one season<\/a>.\n<\/p>\n Director\u00a0Jennifer Kaytin Robinson<\/a>\u00a0(Do Revenge) isn’t carving out new territory here. Her slasher unfolds similarly to its predecessor, with a hook-wielding killer stalking North Carolina teens the summer after they accidentally killed someone in a car accident and covered it up. The difference here, as she told Entertainment Weekly<\/a>, is that she’s leaning into what’s come before and crafting a film that she hopes is “fresh in its nostalgia.”\n<\/p>\n The final product is something of a mixed bag, with EW’s review<\/a> stating that while there’s “a lot that’s enjoyable here” (and the movie has its “tongue firmly in place”), it’s also “preposterously dumb.”\n<\/p>\n Of course, “preposterously dumb” might be exactly what you’re looking for. Teens in slashers are, after all, a bit notorious for being foolish. So, who are the dummies making up the cast of I Know What You Did Last Summer?\n<\/p>\n Keep reading for EW’s I Know What You Did Last Summer cast and character guide.<\/p>\n Chase Sui Wonders as Ava Brucks <\/p>\n Chase Sui Wonders as Ava in ‘I Know What You Did Last Summer’.<\/p>\n Brook Rushton\/ Columbia Pictures<\/p>\n Chase Sui Wonders<\/a> currently stars on the Emmy-nominated Apple TV+ Hollywood satire The Studio<\/a> (2025\u2013present), in which she plays a striving junior executive.\n<\/p>\n She first turned heads in the ensemble of HBO’s short-lived\u00a0Generations\u00a0(2021), which led to roles in the buzzy film\u00a0Bodies Bodies Bodies<\/a>\u00a0(2022) and the Apple TV+ series\u00a0City on Fire\u00a0(2023).\n<\/p>\n Wonders leads the cast of naughty teens as Ava, who returns to Southport to celebrate the engagement of her best pal.\n<\/p>\n “It’s a continuation of this iconic story, and it’s fun and campy and smart,” she told L’Officiel<\/a>. “I play an all-American girl who has a really strong moral code, and although she is very damaged and has some demons, she’s the glue of her friend group. I’m just grateful that [director] Jen [Kaytin Robinson] took a chance on me, because I didn’t see girls like me leading those kinds of movies growing up. And it’s not like I have 20 million Instagram followers, either.”<\/p>\n Madelyn Cline as Danica Richards <\/p>\n Madelyn Cline as Danica in ‘I Know What You Did Last Summer’.<\/p>\n Matt Kennedy\/ Columbia Pictures<\/p>\n Rising star Madelyn Cline<\/a> began her career in a Chuck E. Cheese commercial<\/a>, but her career began in earnest with early roles on Stranger Things<\/a> (2017) and the Joel Edgerton film Boy Erased (2018), starring Nicole Kidman.\n<\/p>\n The actress achieved international success by playing Sarah Cameron on Netflix’s hit Outer Banks<\/a> (2020\u2013present), which helped land her a role in the star-studded ensemble of Rian Johnson’s Glass Onion: A Knives Out Mystery<\/a> (2022).\n<\/p>\n Next up for Cline is a starring role opposite Johnny Depp and Pen\u00e9lope Cruz in Marc Webb’s Day Drinker.\n<\/p>\n Cline helps lead I Know What You Did Last Summer as Danica, one of the teens involved in the fatal cover-up.\n<\/p>\n EW’s critic declared Cline’s character to be “far and away the best thing here,” saying she’s “genuinely hilarious as the snotty-but-lovable Danica; she has a terrific horror movie scream, and during the one or two moments in which the film requires some bona fide dramatic acting out of her, she nails it.”<\/p>\n Tyriq Withers as Teddy Spencer <\/p>\n Tyriq Withers as Teddy in ‘I Know What You Did Last Summer’.<\/p>\n Brook Rushton\/ Columbia Pictures<\/p>\n Tyriq Withers, a former college football player, made a splash in Atlanta<\/a>‘s memorable season 3 episode “Rich Wigga, Poor Wigga.” Following that, he appeared on the Hulu series Tell Me Lies<\/a> (2022) and the 2024 remake of Don’t Tell Mom the Babysitter’s Dead.\n<\/p>\n The actor will next lead the cast of Him<\/a>, a horror film about football players produced by Get Out director Jordan Peele<\/a>.\n<\/p>\n Withers plays Teddy, Ava’s boyfriend and the son of a local real estate developer. “Something I can share about Teddy is he makes sense,” the actor teased in a chat with Interview Magazine<\/a>. When asked to elaborate, he stated, “Do with that information what you will.”<\/p>\n Sarah Pidgeon as Stevie Ward <\/p>\n Sarah Pidgeon as Stevie in ‘I Know What You Did Last Summer’.<\/p>\n Brook Rushton\/ Columbia Pictures<\/p>\n Sarah Pidgeon is an alum of Amazon Prime’s The Wilds<\/a> (2020\u20132022) and Hulu’s Emmy-nominated series Tiny Beautiful Things (2023), not to mention a Tony nominee for theatrical sensation Stereophonic<\/a> (2023\u20132024), starring in both its Off-Broadway and Broadway runs.\n<\/p>\n Her next project is bound to make waves. She’ll soon lead Ryan Murphy<\/a>‘s American Love Story<\/a>, an FX limited series in which Pidgeon stars as Carolyn Bessette, wife of John F. Kennedy Jr.<\/p>\n Pidgeon plays Stevie, a working-class friend of the central teens who works with Freddie Prinze Jr.<\/a>‘s Ray.\n<\/p>\n “What\u2019s cool about horror is that there are so many genres inside of it,” Pidgeon said in an interview with i-d<\/a>. “There can be romance, there can be horror or comedy. There\u2019s drama. I think especially for\u00a0IKWYDLS, it\u2019s about the big kills, but within that, there\u2019s so much opportunity to have character development and laughs. The stakes are so huge that it allows for more things to exist within it, versus, some genres of film that are played really close to the chest and are very intimate.”<\/p>\n Jonah Hauer-King as Milo Griffin <\/p>\n Jonah Hauer-King as Milo in ‘I Know What You Did Last Summer’.<\/p>\n Matt Kennedy\/ Columbia Pictures<\/p>\n Jonah Hauer-King<\/a> rose to prominence as the Prince Eric<\/a> to Halle Bailey’s Ariel in 2023’s The Little Mermaid<\/a>.\n<\/p>\n Before that, Hauer-King starred in several BBC series, including a leading role in BBC One’s war drama World on Fire (2019\u20132023).

Speaking with Collider<\/a>, the actor praised how the filmmakers maintained continuity between the new film and the original.\n<\/p>\n “It’s about 30 years later, and a lot of the vibe is there, but I think also with the new young cast and with Jen Kaytin Robinson, the director, there’s definitely humor in there,” he said. “There’s definitely a modern sensibility, and it feels fresh.\u201d<\/p>\n Gabbriette as Tyler Trevino <\/p>\n Gabbriette in ‘I Know What You Did Last Summer’.<\/p>\n Brook Rushton\/ Columbia Pictures<\/p>\n Gabbriette is a model, musician, and actress who performed with the punk outfit Nasty Cherry before bringing her goth-inspired aesthetic \u2014 some have called it “Succubus Chic”<\/a> \u2014 to the screen.\n<\/p>\n Along with her role as Tyler, a true crime podcaster who crosses paths with our doomed heroes, Gabbriette stars in Idiotka, a film starring Camila Mendes, Anna Baryshnikov, and Julia Fox that debuted at this year’s SXSW Film Festival.<\/p>\n Billy Campbell as Grant Spencer <\/p>\n Billy Campbell at the Los Angeles premiere of ‘I Know What You Did Last Summer’ on July 14, 2025.<\/p>\n Maya Dehlin Spach\/WireImage<\/p>\n After early roles on Dynasty (1984\u20131985) and Crime Story (1986\u20131988), Billy Campbell played the title role in the cult favorite The Rocketeer<\/a> (1991).\n<\/p>\n He went on to appear in films such as Bram Stoker’s Dracula (1992), Gettysburg (1993), and Enough<\/a> (2002), later scoring lead roles on series like The 4400 (2004\u20132007), The Killing (2011\u20132014), and Cardinal (2017\u20132020).

These days, he can be seen on the Australian soap opera Home & Away (2024\u2013present).\n<\/p>\n Orpin plays Wyatt, who EW’s critic described as “a hulking piece of beefcake.”\n<\/p>\n While we won’t spoil it here, anyone who’s watched I Know What You Did Last Summer’s trailer<\/a> knows how things shake out for Wyatt. Orpin himself even joked about it on his Instagram<\/a>.\n<\/p>\n Jennifer Love Hewitt as Julie James <\/p>\n Jennifer Love Hewitt as Julie James in ‘I Know What You Did Last Summer’.<\/p>\n Matt Kennedy\/Columbia Pictures<\/p>\n Jennifer Love Hewitt<\/a>, one of the teen icons of the 1990s, had already starred on Kids Incorporated (1989\u20131991) and Party of Five<\/a> (1995\u20131999) by the time she played Julie James in I Know What You Did Last Summer and its 1998 sequel.\n<\/p>\n In 1998, she scored another hit by leading the ensemble of teen party comedy Can’t Hardly Wait<\/a>. She went on to star opposite Sigourney Weaver in Heartbreakers (2001) and help lead a pair of Garfield films (2004\u20132006).\n<\/p>\n Over the past few decades, Hewitt has landed roles on series like Ghost Whisperer (2005\u20132010), Criminal Minds (2014\u20132015), and 9-1-1<\/a> (2018\u2013present), along with directing and producing work. In 2010, she was nominated for a Golden Globe for her turn in Lifetime’s The Client List<\/a> (2010). She went on to produce a TV version for the network, which aired from 2012 to 2013.\n<\/p>\n Hewitt returns to Southport as Julie and, as the trailer makes clear, gets to play the wise elder for a new generation of potential victims.\n<\/p>\n “I will say it is truly such an honor, at 45, to even be invited back,” Hewitt said in a 2024\u00a0Variety<\/a>\u00a0interview. “To be thought of in that way, to not just move on to the newer, better, younger versions, but [to be offered] to come back and play that part is really cool.”<\/p>\n Freddie Prinze Jr. as Ray Bronson <\/p>\n Freddie Prinze Jr. as Ray Bronson in ‘I Know What You Did Last Summer’.<\/p>\n Brook Rushton\/Columbia Pictures<\/p>\n Like Hewitt, Freddie Prinze Jr. was one of the defining teen actors of the 1990s and 2000s, having led popular films like She’s All That<\/a> (1999), Boys and Girls (2000), and Summer Catch (2001). Young millennials and Gen Z audiences are likely familiar with his turns as Fred in Scooby-Doo<\/a> (2002) and its 2004 sequel.\n<\/p>\n His career, however, has gone some strange and unexpected places. After co-creating, producing, and starring in his own series, ABC’s Freddie (2005\u20132006), he joined the creative staff of WWE<\/a>, helping craft storylines for the professional wrestling juggernaut. In recent years, he served as a host of WWE Rivals (2022\u20132024).\n<\/p>\n In later years, he found his way into the Star Wars universe, voicing Kanan Jarrus in 70 episodes of Star Wars Rebels<\/a> (2014\u20132018). As a voice actor, he’s also contributed to some of the most popular video games of the last 15 years, including Mass Effect 3 (2012) and Dragon Age: Inquisition (2014).\n<\/p>\n In 2002, he married actress Sarah Michelle Gellar<\/a> after meeting on the set of I Know What You Did Last Summer. They have two children, and she somehow saw the new film before he did<\/a>.<\/p>\n “I think what [Robinson and I] both brought to Ray was a lot more vulnerability in this movie,” he told EW<\/a> ahead of the film’s release. “When the s— hits the fan again, so to speak, you kind of see how these characters absorbed all that trauma from the first two movies, and now they’re a sponge getting squeezed, and you get to see what comes out… Nothing felt forced or fake or something that was a note from somebody that didn’t need to be given a note.”\u00a0<\/p>\n Where can I watch I Know What You Did Last Summer? <\/p>\n ‘I Know What You Did Last Summer’.<\/p>\n Brook Rushton\/Columbia Pictures<\/p>\n I Know What You Did Last Summer\u00a0is now playing in theaters.\n<\/p>\n You can stream the original\u00a0I Know What You Did Last Summer\u00a0on MGM+\u00a0and rent its sequels via\u00a0Amazon Prime<\/a>\u00a0or Apple TV+.\n<\/p>\n Sign up for\u00a0Entertainment Weekly<\/a>‘s\u00a0free daily newsletter<\/a>\u00a0to get breaking TV news, exclusive first looks, recaps, reviews, interviews with your favorite stars, and more.\n<\/p>\n
