Yesterday’s Conan O’Brien finale (the New York version) officially kicked off the countdown for his successor’s premiere.

Beginning next month, a host of A-list celebrities will help launch Late Night with Jimmy Fallon. Tina Fey (NBC star), Donald Trump (NBC star), Drew Barrymore (his Fever Pitch costar) and Cameron Diaz (why??) are among the names slated for Week 1.

Unfortunately, the SNL vet has elected to get the ball rolling with one of the most difficult interviewees out there: Robert De Niro. (I strongly suggest Fallon dissect Brian Williams’ awkward attempt first.)

Late Night debuts @ 12:30 A.M. on March 2nd.
