James Gunn is developing a new Superman movie for DC Studios.
The movie will not star Henry Cavill and will focus on an earlier part of Superman's life.
Michael Rosenbaum, who played Lex Luthor on "Smallville," wants to be considered for the role.
The movie will not be an origin story and will focus on Superman living in Metropolis.
Henry Cavill confirmed he will not be returning as Superman.
Cavill will executive produce and star in a new "Warhammer 40K" cinematic universe for Amazon Studios.
Gunn's Superman movie will include "major characters."
Michael Rosenbaum was suggested as a potential Lex Luthor by a fan on Twitter.
Rosenbaum replied to the fan, saying he hopes he'd be in the running for the role.
Rosenbaum played Lex Luthor on "Smallville" for seven years.
Cavill wishes the best of luck to James Gunn and the new DC Universe.
