Jimmy Fallon's first guests on 'The Tonight Show': Will Smith, U2

Jimmy Fallon takes over "The Tonight Show" on Feb. 17, but one must have guests if one is to have one's own "Tonight Show," and NBC announced the first of them Sunday: Will Smith and... U2.  

Smith headlines the upcoming movie "Focus," and U2, which also needs no introduction -- and is also fresh off a Golden Globes win for the song "Ordinary Love," from "Mandela: Long Walk to Freedom -- will release its first album in five years later in 2014.
