The good times seem quite good for Hugh Jackman and Kate Hudson in the trailer for Song Sung Blue.

Focus Features releases writer-director Craig Brewer‘s fact-based film in theaters nationwide Dec. 25. Michael Imperioli, Ella Anderson, King Princess, Mustafa Shakir and Hudson Hensley round out the cast.

Based on a true story, Song Sung Blue centers on a pair of struggling musicians whose luck changes when they decide to form a Neil Diamond tribute band.

“I’m not a songwriter,” Jackman says candidly in the trailer. “I’m not a sex symbol. I just want to entertain people.”

Later, Hudson tells him, “You don’t want to be a Neil Diamond impersonator. You want to be a Neil Diamond interpreter.” This leads Jackman to enthusiastically respond, “I was looking for the right way to say it, and you just came right out and said it.”

Brewer (Dolemite Is My Name) helmed Song Sung Blue from his own script that is based on a 2008 documentary of the same name. He produces the new feature alongside John Davis and John Fox.

Diamond released his single “Song Sung Blue” in 1972, and it hit No. 1 on the Billboard Hot 100. Diamond is known for such other notable hits as “Cracklin’ Rosie,” “Longfellow Serenade” and “Sweet Caroline.”

Jackman starred alongside Ryan Reynolds in last year’s box office smash Deadpool & Wolverine, and his forthcoming features include Three Bags Full: A Sheep Detective Movie and The Death of Robin Hood. Hudson stars on the Netflix series Running Point, which has been renewed for a second season.
