Joseph Gordon-Levitt could be playing Batman in upcoming movie Justice League.
The US actor played policeman John Blake - who was eventually revealed to be the superhero's sidekick Robin - in this year's The Dark Night Rises, with Christian Bale as the caped crusader.
And according to Hitflix.com, sources say Joseph will "absolutely" be taking on the Batman role in the DC Comics adaptation, which sees superheroes unite to fight evil powers.
The blog also suggests Batman could make an appearance in Zack Snyder's upcoming Warner Brothers Superman reboot Man Of Steel, potentially in a post-credits sequence.
Joseph, who found fame in the sitcom 3rd Rock From The Sun, is currently promoting new biopic Lincoln, in which he plays the son of US president Abraham Lincoln.
Justice League is expected to be released in 2015.
