HOLLYWOOD, Calif. — It's probably a good idea not to ask Mel Gibson about his controversial past.

The 54-year-old actor got testy with WGN's Dean Richards after the entertainment reporter inquired: "Do you think the public will perceive you any differently after all that's been in the news about you?"

"That's almost four years ago, dude. I've moved on. I guess you haven't," snapped Gibson, who was famously pulled over for a DUI in 2006 and allegedly made anti-Semitic comments during his arrest.

"I certainly hope so," added Gibson about his fans forgiving him. "It is a while back and I've done the necessary mea culpas. Let's move on, dude. Come on."

Gibson, who was doing a satellite interview to promote his new movie, Edge of Darkness, ended the uncomfortable chat by calling Richards an "a--hole" as he signed off.
