Following the release of Zack Snyder's film, it was strongly rumoured that Superman's iconic nemesis would feature in the sequel, with Strong named as one of several contenders for the role.
Asked by Digital Spy whether there was any truth to the rumours, Strong responded: "All I can say is... watch this space."
It was announced at Comic-Con last month that the Man of Steel sequel would feature Batman, and would draw heavily on Frank Miller's The Dark Knight Returns, in which a grizzled Bruce Wayne faces off against Superman.
Christian Bale will not return to play Wayne, and it has been reported that Josh Brolin, Ryan Gosling and Matthew Goode are among those being considered to take over the role.
