5. LL Cool J vs. Jamie Foxx
Showdown: It was supposed to be your standard Hollywood fight scene. But during filming for director Oliver Stone’s testosterone-propelled 1999 pro football drama Any Given Sunday legendary rapper turned thespian LL Cool J had other ideas. The NCIS Los Angeles star took staying-in-character to Robert De Niro levels when he continued to scrap off camera with future Oscar-winning co-star Jamie Foxx even as Stone yelled, ‘Cut!’ Swaggering starting quarterback Willie Beamen…um, we mean, Foxx, filed assault charges against James Todd Smith. "It wasn't Jamie and I fighting. It was our characters," an all-too serious LL later explained. Now that’s dedication…we think.
Winner: Jamie called the cops. Enough said.
