Director Paul Greengrass has shed light on his previous involvement in a once-proposed X-Men vs. Fantastic Four movie for 20th Century Fox.

"They did talk to me about it," Greengrass said on the Happy Sad Confused podcast. "I wouldn't say I was attached. [We] talked, and I thought about it, and in the end..."

Previously, screenwriter Zack Stentz revealed that he and writing partner Ashley Edward Miller had penned a script for Fox in 2011 that would have featured all of the Marvel Comics characters that the studio had the film rights to. "It used the X-Men. It used the Fantastic Four. It used Daredevil. It used Deadpool. Daredevil was still at Fox at the time," Stentz explained. "We almost had Paul Greengrass directing it which would've been so cool but he had another project to do instead. It didn't end up going but it was a script I was really proud of and it would've been really good."

This project was eventually revealed to be an X-Men vs. Fantastic Four movie in the mold of Mark Millar and Steve McNiven's Civil War storyline. This conflict would have put the X-Men and Fantastic Four on opposing sides and included a duel between Wolverine and Mr. Fantastic. A post-credits scene would have reportedly teased another mega-event movie based on the Secret Invasion storyline.

The project never moved forward after the box office success of X-Men: First Class, another Fox/Marvel movie penned by Stentz. Fox also commissioned a separate script for an X-Men vs. Fantastic Four movie by Warren Ellis, details of which have not yet surfaced.
