10 Incredible Movie Scenes You Won't Believe Weren't Faked

3. The Crew Really Were Weightless - Apollo 13

For any space-set movie, you're going to havd to expect some zero g sequences (even if it's just in the astronaut training montage, because it always looks so good on camera). When it comes to a considerable number of those scenes, you'd think that a director would use harnesses or digital manipulation to keep control of the scenes (and their costs).

But that wasn't the case with Apollo 13, which required a fair amount of weightless sequences. Instead, the studio got an assist from NASA, whose delightfully-nicknamed Vomit Comet training plane was borrowed to achieve the scenes.

The plane - a KC-135 - moves up and down quickly to achieve weightlessness inside and was turned into a soundstage for Apollo 13. Incredibly, it took around 600 parabolic arcs to get everything shot, which must have played merry hell with the actors' stomachs.
