They say to let sleeping dogs lie, but one sleeping dog has laid down for bit too long. Donnie Yens Sleeping Dogs adaptation is no more, the actor shared with Polygon this week.Fans of the 2012 Hong Kong-set action game have been waiting for years for an update on a live-action film adaptation. First announced in 2017, the Sleeping Dogs movie was to star Yen, who rose to international fame in the Ip Man franchise and made a Hollywood splash in Star Wars: Rogue One, as game protagonist Wei Shen. In 2018, Yen said the movie was in motion, and at one point, Indonesian gore maestro Timo Tjahjanto (The Night Comes for Us, The Shadow Strays) was in talks to direct. That would have been quite the appealing combination of talent for an adaptation of a beloved title, but as Yen shared on a Zoom call this week, the project is no longer in the works at least as far as the Hong Kong legend is concerned.I spent a lot of time and did a lot of work with these producers, and I even invested some of my own money into obtaining the drafts and some of the rights, Yen says. I waited for years. Years. And I really want to do it. I have all these visions in my head, and unfortunately I dont know, you know how Hollywood goes, right? I spent many, many years on it. It was an unfortunate thing.Well, onto better things.The news likely wont come as a surprise to fans the lack of any release date announcement or further information wasnt promising but its disappointing nonetheless. Sleeping Dogs always seemed like a natural fit for Yen, both as a star and potentially as a director its a martial arts-infused Hong Kong crime thriller clearly inspired by many of Yens HK classics, and there are few more skilled leading men at delivering the kind of action you would expect.Its not the first Sleeping Dogs project to stall in the development phase either. A planned sequel and spinoff were both cancelled in the 2010s, which means Sleeping Dogs fans will have to settle for the great original game and its many DLC offerings or some of the terrific movies the game was inspired by.Yen remains busy. His new movie, the hybrid courtroom drama/action thriller The Prosecutor directed and starring the actor, is out in theaters starting Jan. 10. Yen has also been attached to a John Wick spin-off centered on his John Wick: Chapter 4 character Caine, and hes working on new entries in both the Ip Man and Flash Point franchises.
