HARRISON FORD is back in the highly anticipated 'Indiana Jones and the Kingdom of the Crystal Skull,' in theaters everywhere May 22, and the rugged star arrived on his own motorcycle for his exclusive interview with our own MARY HART!

So how does it feel to put on the fedora, the leather jacket and crack the whip almost 20 years after the last Indy movie? Harrison tells Mary, "It just all comes back very easily."

Plot details are being kept tightly under wraps for the fourth installment of the adventure series, produced by GEORGE LUCAS and directed by STEVEN SPIELBERG, but the 65-year-old star assures Mary that he wasn't too old to return to the famous role.

"I'm aware of my advancing age, but I wasn't worried," he confides. "I don't do stunts [but] I do as much physical action as I can."

Harrison keeps mum over any storyline details -- like whether or not SHIA LaBEOUF plays his son in the movie or not -- but he's happy to talk about co-star CATE BLANCHETT, who is decked out in a black wig and gives Indy a run for his money as KGB agent Irina Spalko.

"There's plenty of action to go around; action between the two of us," he says. "But our contest is mostly psychological."

And of the return of KAREN ALLEN, who played Indy's love interest in 'Raiders of the Lost Ark,' Harrison says, "Karen is the same old Karen she was 20 years ago; independent and feisty and fun."

There were early rumors circulating saying that Harrison's real-life love, CALISTA FLOCKHART, was going to be in the film, but he dismisses that as strictly "Internet speculation."

And when asked if he feels like he has something riding on the movie personally, Harrison jokes, "Well, I mean, I stand to make hundreds and hundreds of dollars."
