"In Life of Brian, the line after "yes, we're all individuals", "I'm not!" was ad-libbed, bumping the extra up in pay for now having a distinct speaking role."

"In Apollo 13, they filmed in NASA's "vomit comet", a plane that flew at high altitudes and would create parabola movements to simulate a short period of low gravity. They built the Apollo spacecraft set inside the plane and almost every scene featuring zero gravity was filmed in the plane. They flew over 500 times in the parabola. From the time that low gravity simulation would start, they would only have 23 seconds to unstrap from restraints, set up a shot, roll, and then strap back in. They completed all of these flights in 13 days. THE MOST UNDERRATED MOVIE FACT OF ALL TIME! The only movie ever to film in actual Zero Gravity."
