Celebrities that you are surprised have never hosted SNL before in its 50 years?

Robert Downey, Jr. (especially since he was on the show in his younger days)

Johnny Depp (though I think I heard he was offered once or twice but said no both times)

Tia Carrere (given the success of Wayne's World and its sequel)

Katy Sagal

Milla Jovovich

Joe Rogan

Keanu Reeves

Sir Gary Oldman (he was scheduled to host back in 1992 but had to drop out at the last minute to my understanding)

Eddie Izzard

Kate Beckinsale

Michael Cera

Ron Perlman

John Leguizamo

Cobie Smulders (considering how popular How I Met Your Mother was and that she is married to Taran Killam)
