Clint Eastwood continues to be one of the most prolific directors working today, having put out essentially a movie a year for the past few decades now. This year he has already released The 15:17 to Paris, but just in time for awards season he has a second project hitting theatres as well. The Mule finds him back in a starring role in one of his own films for the first time since 2008’s Gran Torino and there is speculation that it could be his last. Based on the true story of an 80-year-old WWII veteran who becomes a drug runner for a Mexican cartel, the movie co-stars Bradley Cooper along with Taissa Farmiga, Michael Pena, Laurence Fishburne, Clifton Collins Jr. and Dianne Wiest. The Mule hits theatres on Dec. 14th; check out the trailer after the jump and see what you think.
