Director Zack Snyder has fuelled rumours that the character Aquaman will appear in the upcoming Batman V Superman movie.
There have been reports that Game Of Thrones star Jason Momoa is in line to play the Justice League superhero in Dawn Of Justice.
Filmmaker Zack has now added to the speculation by calling in to a US radio show after the character was teased, insisting that Aquaman has "cool abilities", reported E! News.
He told the hosts of the Detroit station: "People are like, 'Oh, what? Does he talk to animals? Cause that seems like what he does. Or fish?' The cool thing with Aquaman is he's Triton, so you have to realise that [he] could cut the flesh of Superman if they came in contact."
But the director stayed tight-lipped about whether Aquaman would be joining Ben Affleck's Batman and Henry Cavill's Superman in the film, saying: "It's not to say that he's in the movie or anything like that.
"But he has the potential to be bad a**."
Earlier this year actor Jason was quizzed about the Aquaman reports when he was interviewed by US TV host Jimmy Kimmel.
When asked about the role, the star said: "Those are all rumours," although he didn't deny them.
Jason, who played Khal Drogo in Game Of Thrones, later added: "That would be pretty exciting. What do you think? We'll just have to wait and see. I don't know."
Batman V Superman: Dawn Of Justice will be released in cinemas on March 25, 2016.
