After Ali tripped over Wepner's foot, the referee ruled it as a knockdown, but Ali was awarded a technical knockout in the 15th round to retain his title. Wepner's real-life story is coming to the big screen, with Liev Schreiber playing Wepner in "Chuck," which opens on Friday, May 5, 2017, in New York and Los Angeles before expanding nationwide.
