"It was a tricky shoot but you know... When you know when you're shooting it that a film isn't going to be what you want it to be (sic)? That was not the case at all," she told British newspaper The Times.
When asked if she has seen the film, Mara adds, "No, but I will eventually," but adds that the movie's harsh reviews have made her feel "a little bit gun-shy".
Despite Fantastic Four's troubles, Mara, who is rumoured to be dating her co-star Jamie Bell, says that those involved "really had each other's backs,".
"That's the thing that makes me most bummed because we have no idea if we'll ever make another one."
