EXCLUSIVE: Young Sherlock is attracting attention ahead of its Prime Video debut, and the series trailer has now laid claim to a record audience.

The trailer, which premiered on February 5, racked up 223M views in the first seven days, per data from Wavemetrix shared with Deadline. That makes it Prime Video’s most-watched series trailer ever in that timeframe.

For context, it now ranks above the trailer performance for some of Prime Video’s most popular series. Young Sherlock now sits healthily in first place, followed by the first trailer for The Lord of the Rings: The Rings of Power Season 1, which managed 163.6M views in seven days, and a Season 2 trailer for The Summer I Turned Pretty that got 151.8M.

The trailer teases what’s to come from Young Sherlock, chronicling the detective’s origin story. Hero Fiennes Tiffin stars as the defiant sleuth who is framed for murder and gets involved in a global conspiracy that alters the course of his life. 

In Young Sherlock, Holmes is a disgraced young man – raw and unfiltered – when he finds himself wrapped up in a murder case that threatens his liberty. His first ever case unravels a globe-trotting conspiracy that changes his life forever. Unfolding in 1870s Oxford and venturing abroad, the series will expose the early antics of the anarchic adolescent who is yet to evolve into Baker Street’s most renowned resident.

The series also stars Dónal Finn, Zine Tseng, Joseph Fiennes, Natascha McElhone, Max Irons and Colin Firth.

Ritchie directs the first two episodes and executive produces Young Sherlock. The show comes after he helmed Sherlock Holmes (2009) and Sherlock Holmes: A Game of Shadows (2011).

Created for television and executive produced by showrunner Matthew Parkhill, EPs include Dhana Rivera Gilbert, Marc Resteghini, Simon Maxwell, Ivan Atkinson, Simon Kelton, Colin Wilson and co-executive producers Harriet Creelman and Steve Thompson. Motive Pictures led physical production for Young Sherlock.
