In a new interview, X-Men: First Class director Matthew Vaughn has opened up about his plans for a trilogy of X-Men movies, including who he wanted to play a young version of Wolverine in the '70s.

The director told Coming Soon that he originally wanted to follow up the '60s period piece First Class with a '70s film starring Wolverine and that era's X-Men. According to his original plan, that would've led to a "Days of Future Past" movie that brought all of the X-Men's cinematic incarnations together.

"When I finished the “Days of Future Past” script with it ready to go, I looked at it and said, “I really think it would be fun to cast Tom Hardy or someone as the young Wolverine and then bring it all together at the end.”

While he wanted to end his X-trilogy with Days of Future Past, 20th Century Fox didn't agree with his plan. Vaughn said that the studio subsequently made 2014's X-Men: Days of Future Past next. While original X-Men director Bryan Singer returned to the franchise for that film, Vaughn moved on to other projects, including the Kingsman franchise. Days of Future Past was followed up by 2016's X-Men: Apocalypse and director Simon Kinberg's upcoming Dark Phoenix.

After appearing in all previous X-Men movies and making a cameo in First Class, Hugh Jackman continued to portray Logan in Days of Future Past up through 2017's Logan.

Even though Hardy missed out on his chance to play a young Logan, the actor still starred as the Batman villain Bane in 2012's The Dark Knight Rises. He eventually starred as another iconic Marvel antihero with the titular role in 2018's hugely-successful Venom.

Directed and written by Simon Kinberg, Dark Phoenix stars James McAvoy, Michael Fassbender, Jennifer Lawrence, Nicholas Holt, Sophie Turner, Tye Sheridan, Alexandra Shipp, Kodi Smit-McPhee, Evan Peters and Jessica Chastain. The film arrives June 7.
