Liev Schreiber Got Hit Over 800 Times for 'Chuck' - Watch Trailer!

Liev Schreiber went above and beyond to star as real-life fighter Chuck Wepner, who fought Muhammad Ali at the peak of his career but then spiraled into a life of alcohol and cocaine, in his latest film.

To make the boxing scenes more realistic in Chuck, the 49-year-old actor decided to do the all the fights himself, and at one point was left with hazy vision after taking 800 punches.

“By the end of the fourth day of shooting, I wasn’t seeing so good, but I think it was worth it,” Liev joked (via NY Daily News). “What really grabbed me about ‘Chuck‘ was the pitfall of celebrity and fame. His was a kind of cautionary tale about the dangers of that particular kind of narcissism – the desire to be loved by the anonymous mob and not the individuals to whom we are truly connected, which is something I think a lot of people can relate to.”
