Trivia: The Apollo 13 mission set a record for the greatest distance from Earth ever achieved by mankind. This occurred because unlike the other Apollos, Apollo 13 did not make a burn behind the moon to drop into lunar orbit. The free-return trajectory the mission followed took the spacecraft farther behind the moon than any other mission.
Trivia: When Bill Paxton vomits they used Beef-a-Roni stew for the vomit. Since they only had to use a spoonful for each take, they had half a can left at the end of the day. After losing a bet with Tom Hanks, Bill had to then eat the rest of the can. Bill Paxton confirmed this personally at an autograph signing.
Trivia: In an interview, Ron Howard revealed that, after a test screening, he was concerned about an audience reaction card that rated the film as "terrible" until he read a comment on the card dismissing the ending as "more Hollywood b*llsh*t", saying that had it happened in real life, the astronauts "would never have survived".Tailkinker
Trivia: Many people have claimed that Lovell's LEVA (Lunar Extra-Vehicular Visor Assembly) is incorrect because it shows a Navy Anchor and "No LEVA had that." Interestingly enough, Jim Lovell's flown LEVA had a blue box containing the Navy Insignia, a custom made helmet and the only one of its kind in the entire program. NASA has a photo of it on their Apollo Lunar Surface Journal which can be viewed here: http://www.hq.nasa.gov/alsj/a13/a13LovellVisor.jpg.
