As one of the potential witnesses in his own trial, Mel Gibson could be cross examined in court by the very man accused of stalking him. Zack Sinclair, 34, is defending himself in court, setting up the potential face-off with Gibson. Sinclair is accused of repeatedly showing up at Gibson's home, following him to church and even demanding the Oscar winner pray with him.

But despite the trial's attention, Gibson told "Good Morning America's" Diane Sawyer that he's looking forward to stepping back into the spotlight. "I think it's time to get back in the saddle," he told Diane.

Gibson will play a biker in his first major role since 2002's "Signs." It's a far cry from his heartthrob image. "I'm a hairy middle-aged man," he insisted. "I think the heartthrob thing is well and truly over."

But what is still going strong is "The Passion of the Christ." Mel has actually re-cut the movie, toning it down for an upcoming re-release just before Easter.

So does this mean the people who said it was too violent were right? "No, I don't think so," Gibson said. "That's the way I wanted it, I just wanted to make it available to a wider audience."

The "Passion" is one of the highest grossing movies of all time, but Mel was snubbed by Oscar, although he insisted, "I'm not disappointed because I didn't expect anything."

Gibson's stalking case is expected to continue in Los Angeles until next week.
