10 Insane Movies That Were Almost Made

10. Tom Cruise/James Cameron Space Movie

The Movie: A project we only recently heard about, legendary Hollywood duo James Cameron and Tom Cruise were, at one point, considering shooting a big-budget movie together.

But as you'd expect from two masters of spectacle, this wouldn't have been your average blockbuster. Far from it. In reality, the plan was to jet off into space and shoot the entire thing up there. Cameron told Empire that he had a contract in 2000 to go to the International Space Station and shoot a 3D documentary. So, he figured why not make a proper movie while he was up there?

He didn't disclose any story ideas, but given his penchant for delivering stunning, awe-inspiring visuals, and Cruise's commitment to ensuring his movies look and feel as realistic as possible, this would have been quite an experience.

Why It Wasn't Made: Again, Cameron didn't mention why this never came to be, but from his comments, it's clear that this venture was simply an idea, and nothing more.

“I actually talked to [Tom Cruise] about doing a space film in space... I said, ‘Tom, you and I, we’ll get two seats on the Soyuz, but somebody’s gotta train us as engineers.’ Tom said, ‘No problem, I’ll train as an engineer.’ We had some ideas for the story, but it was still conceptual.”

With Cameron busy making endless Avatar movies, it remains to be seen if he'll ever get the chance to revisit this one.
