Roman Coleman, the career-defining role that journeyman Matthias Schoenaerts (Rust and Bone, The Drop) has been waiting for, does not disappoint. Finally, the 42-year-old actor you’ve seen in the background here and there and everywhere gets his opportunity to truly lead a movie. As the hardened felon-turned-horse trainer proves, anything can happen to anyone, given the right circumstances. The Mustang is a brilliantly directed movie by first-time director Laure de Clermont-Tonnerre. Roman seems to desire to serve his time quickly and with as little human interaction as possible. He is nearly unrecognizable with his shaved head, as well as chiseled, tattooed body. But his problem with the latter leads to a longer than expected stay, and his explosive anger to go with that machine of a body suggests that he might not be going anywhere anytime soon.
