Thanks to some displaced anger, Paul Rodriguez is alleging Will Smith was a total jerk to him on the set of Ali.

In an interview with San Diego radio station Rock 105.3, Rodriguez says that before the biopic, the two actors had a pleasant rapport and enjoyed working together on other projects.

However, after Rodriguez was cast to play Muhammad Ali’s cornerman Ferdie Pacheco, the real Pacheco showed up on set drunk one day and proceeded to attack Smith so incessantly with racial slurs they had to call security.

Smith was understandably upset by the incident, and from that day forward reportedly projected his ill will toward Pacheco onto the man playing him.

“He was an a-hole … he started saying offensive stuff to me,” Rodriguez recalls. “Maybe it was the steroids he was using to beef up.”
