It's hard enough to star in a remake of a movie that came out just a decade ago, but when you’re starring in a beloved Marvel comic adaptation that’s a favorite of guru Stan Lee? The pressure is on.

ET spoke with the cast of the Fantastic Four reboot, Miles Teller, Jamie Bell, Kate Mara, and Michael B. Jordan, about their upcoming reboot and the pressure to please fans, creators, and producers alike.

"It's intimidating to know how passionate the fans are," admits Mara, who stars as Sue Storm, a.k.a. The Invisible Woman. "We don't wanna let the fans down."

"We're not superheroes yet, because it's such an origin story," says Jordan, who plays Johnny Storm/Human Torch, of the reboot. "We're just teenagers kinda going through life just trying to handle this new-found power so we don't really have too much pressure to be superheroes just yet. Towards the end of the film, maybe the second sequel, we might feel that a little bit more, but I think we do feel the pressure of just wanting to do a great film."

Pressure to please the comic fans is tough enough, but Jordan faced far more than his share when he was cast as Johnny Storm, with some fans flooding social media and message boards with racist backlash. Jordan responded with an op-ed in Entertainment Weekly.

"To the trolls on the Internet, I want to say: Get your head out of the computer," the actor wrote back in May. "Go outside and walk around. Look at the people walking next to you. Look at your friends' friends and who they’re interacting with. And just understand this is the world we live in. It’s okay to like it."

"I got a lot of positive feedback from it," Jordan told ET of the response to his article. "Across the board, a lot of positive feedback."

It seems Jordan’s Fantastic Four castmates have learned something from the actor's experience, as Teller offers his advice to other actors who take on beloved superhero roles.

"Stay off the Internet," Teller says. "It's bigger than you are. The Fantastic Four has been around for a long time, and it will continue long after we stop playing these characters. So yeah, just understand that."
