The real-life Rocky who floored Ali

When part-time fighter Chuck Wepner is given a shot to fight heavyweight champion Muhammad Ali in 1975, no one gives him a chance. But his heroism in the ring knocked down all expectations, including those of the champ, and inspired a cinematic saga in the process. He speaks to Ben Wyatt about the build up and the big fight itself.

This is a Comuniqé production for the BBC World Service.
