The manager for “Man of Steel” star Henry Cavill says a new standalone sequel to the Superman film is in the works.

Cavill reprised his role as Superman earlier this year in “Batman v Superman: Dawn of Justice” and is currently filming a Justice League film which is due out next year.

Cavill’s manager Dany Garcia tells Newsweek that Cavill is “beginning to expand” the Superman world and is in very early development for the standalone sequel.

Both “Man of Steel” and “Batman v Superman” received tepid reviews from critics but were box office successes. Warner Bros. has at least 10 films in the works to expand the DC Comics Universe, including “Wonder Woman,” ”Aquaman,” ”The Flash” and a standalone Batman.

The studio declined to comment on the Newsweek report.
