The latest rumours surrounding Batman v Superman suggest the heroes will be joined by an Amazonian woman who's handy with a lasso of truth.
Geek website Bleeding Cool has posted a casting call for the Man of Steel sequel that fans say points to an appearance by Wonder Woman.
According to the site, director Zach Snyder is "looking for a new female lead ... a phsyically strong woman somewhere between 25 and 33".
"The discussion in some agencies who have been submitting actors for this role is that they're sending up candidates for the role of Wonder Woman. They don't know that it's her, it's just become their expectation, or at least a rumour that's coloured their conception.
"Warner Bros, as you might expect, are refusing to confirm this, even to the agents they're negotiating with. But it seems that they've also failed to deny it."
It could be Snyder is looking for the one of the film's villains but an appearance by Wonder Woman could open the door to a Avengers-style superhero team-up film, Justice League.
Batman v Superman writer David S Goyer, who also penned all three Christopher Nolan Batman filsm plus Man of Steel, recently told AP that the film is "a bit a further along than what I think people realise".
He was also on Team Clark Kent when asked who would win in a fight between Batman and Superman.
"Most comic book purists would say Batman, because he is the ultimate strategist. Even though it makes no sense whatsoever. If Superman just flicked his finger, Batman would be done for."
When asked if he was working on Justice League, he was coy: "Might be, can't say."
Batman v Superman is due to hit cinemas in July 2015. It will star Ben Affleck as Batman and Henry Cavill as Superman.
