Fox's most recent attempt to bring "Fantastic Four" to the big screen did not work out so well; the film flopped in theaters, opening at #2 and only earning $56 million domestically. Fox later pulled the planned 2017 "Fantastic Four" sequel from it's schedule.

"FF" producer Simon Kinberg still holds out hope for more of the franchise, as he revealed in an interview with Den of Geek -- and he's well aware of the response the first film received.

"We didn't make a good movie, and the world voted, and I think they probably voted correctly," said Kinberg, adding that Fox "made many mistakes" with "Fantastic Four" -- "mistakes that we learned from and we wouldn't repeat."

Kinberg hopes that the "Fantastic Four" gets another chance on the big screen -- and he wants to keep the film's cast intact. "We want to make another 'Fantastic Four' movie. We love that cast -- I mean if I were to say to you now Michael B. Jordan and Miles Teller, and Kate [Mara] and Jamie [Bell] are great actors -- we love that cast. I love the comic, I mean I love it almost as much as X-Men."

The producer added that a sequel would not be as dark in tone as the 2015 film, and would instead "try to be truer to the essence of the tone of Fantastic Four" which is "brighter, funner, more optimistic." Kinberg added: "I think we tried to make a darker Fantastic Four movie, which seemed like a radical idea but we were kind of messing with the DNA of the actual comic instead of trusting the DNA of the comic."

No official update has been given regarding a "Fantastic Four" follow-up, but Kinberg says he's "working really hard on figuring that out. Nothing would make me happier than the world embracing a Fantastic Four movie."
