Though Batman trilogy director Christopher Nolan has said that "The Dark Knight Rises" would be his last work with the series, the ending of the third film had fans wondering if Joseph Gordon-Levitt's John Blake (a.k.a. Robin) would be back for his own spin-off film.
"Why would they set up a whole thing at the end and then just give up on the franchise?" Kimmel asked Gordon-Levitt on "Jimmy Kimmel Live" Tuesday night, referring to the film's final moments, when Blake is given access to the Batcave following Bruce Wayne's retirement.
