What do you do when you're Oprah Winfrey, you're ending your mega-successful show in about a year and you want your audience to surge during the May sweeps? First, you get Tom Cruise to return to your program. Then, you fill in around that.

That's exactly what Oprah is doing on her show. On the May 14 installment Cruise, along with Cameron Diaz, will show up to promote their upcoming action-comedy 'Knight and Day.' Don't look for too much couch-jumping by Mr. Cruise, though, as he has a movie to promote.

Surrounding Cruise's appearance are a bevy of personalities, both in and out of Hollywood, that will stop by to chat with Miss O. This includes Simon Cowell, Dolly Parton, former First Lady Laura Bush, Julia Roberts and, for all of you screaming teenage girls out there, Justin Bieber. The full schedule can be found after the jump.

Wrap up 2009 with a glimpse of what's happening over at Moviefone's Inside Movies:

Tom Cruise returns to butt-kicking form in 'Knight & Day,' an action-comedy due next summer co-starring Cameron Diaz. Check out the trailer.

It was a record-breaking Christmas holiday at the box office, led by 'Avatar's' $75 million weekend take.
