Jared Leto‘s Joker could be making a cameo in Justice League if rumours are correct.
The actor is currently in the UK causing speculation that he was in the country to film scenes for Zack Snyder’s superhero movie.
As Digital Spy, the film is being shot in the UK at the moment and features Ben Affleck, Henry Cavill, Gal Gadot, Ezra Miller and JK Simmons.
Justice League will be released on November 17, 2017.
Leto’s Joker, meanwhile, is due to appear in Suicide Squad, which is released on August 5. The actor said previously that he had studied “horrendous crimes” while researching for the role.
“To the Joker, violence is a symphony,” he said. “This is someone who gets an extreme reward from the act of violence and manipulation. Those are the songs he sings and he is very in tune with what makes people tick.
“I did meet with people that were experts, doctors, psychiatrists that dealt with psychopaths and people who had committed horrendous crimes, and then I spent some time with those people themselves, people who have been institutionalized for great periods of time.”
