Brown is one of my favorite character actors, and he has been in a ton of films and TV shows over the years. One of the most recent films he was in was Homefront with Jason Statham. He's also been in things such as The Shawshank Redemption, Carnival, and has done a ton of voice work. As for Wu, he's been in films such as Tai Chi Zero, Chinese Zodiac, and Europa Report.
The first script for the film was written by Charles Leavitt, which was then rewritten by Jones. Production is set to begin as planned in Vancouver this January, and it will be released on March 11th, 2016!
