The comedy duo along with their fellow cast mates stopped by Conan O'Brien's show on Wednesday night to chat about their new flick, which debuts this weekend. The late-night host and celebrity stakeholder in the #UFC had nothing but praises for Fist Fights' climactic battle scene, calling it "the most epic fist fight of all time" and the "biggest fist fight that's ever occurred on film."
Ice Cube agreed with O'Brien's assessment and broke down what went into making his showdown with Day happen.
"We fought more than Rocky in this movie," the rapper-turned-actor said. "The fight went eight days. We got bumps and bruises. Charlie keeps telling me I slammed him into a bus."
The It's Always Sunny in Philadeplhia star has probably spent the most time with fighters, working with the likes of Donald "Cowboy" Cerrone for an episode of the FXX sitcom, as well as throwing down with Nate Diaz for a Fist Fight promo. He also spent time with training with Yves Edwards to prepare for the comedy.
As for Ice Cube, he got a chance to work with welterweight champ Tyron Woodley during filming for Straight Outta Compton, and also recently tested his sumo skills against light heavyweight champion Daniel Cormier.
Fist Fight hits theaters on February 17.
