Oprah Winfrey’s Oscar Special – if nothing else – will be unique. The talk show host is bringing together Academy Award winners and nominees to interview each other.

Who are the who’s who? Halle Berry (Actress in a Leading Role – Monster’s Ball) and Penelope Cruz (Supporting Actress winner – Vicky Cristina Barcelona).

Director James Cameron will sit down with his Avatar stars, Sam Worthington, Zoe Saldana and Sigourney Weaver.

Ben Affleck and Matt Damon (Original Screenplay winners – Good Will Hunting) chat it up with Leading Actor nominee, Jeremy Renner from The Hurt Locker.

Plus Fatal Attraction co-stars, Glenn Close and Michael Douglas reunite for an on-camera discussion.

And while we’re on the subject of guest coups, Winfrey is set to interview the American missionaries who were just released from custody in Haiti. The missionaries were cut loose after being leveled with charges of child kidnapping for trying to take 33 kids out of the earthquake-ravaged area.

Jim Allen and his wife, Lisa Allen will appear on Winfrey’s talker, The Oprah Winfrey Show today.

The Oprah Winfrey Oscar Special airs prior to the Academy Awards, March 3rd, 10:01 p.m. ET/PT on ABC.
