In 1992, Jon Seda landed his first role in the movie "Gladiator." No, we aren't talking about the film where Russell Crowe plays a vengeful Roman soldier. This "Gladiator" was a boxing film starring Cuba Gooding Jr. where Seda played one of the many boxers competing in illegal fights for some extra cash. It was a part that he was made for, as Seda previously had been a successful amateur boxer. In 1989, Seda was the runner up for the New Jersey Golden Gloves (the biggest amateur boxing title), and had a record of 21 wins and 1 loss.
"Sometimes I have dreams and they feel so real that I wake up and I go, 'Oh, wait a minute, I'm not boxing anymore, I'm actually acting,'" Seda said in an interview with American Profile. "I think about it a lot. To me, it's kind of like an unfinished chapter. I get to play a lot of boxing roles in films, and experience that. But I think about it all the time. Who's to say? I could've gotten knocked out in my first professional fight and never had a career."
Despite hanging up his gloves years ago, the boxing world has not forgotten Seda. In 2015, he served as the Grand Marshal of the Boxing Hall of Fame Parade of Champions (via Rome Sentinel). With that honor on his resume, Seda has officially gone down in the annals of boxing history.
