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".
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.
Trivia: During the broadcast, Fred starts playing the song "Spirit in the Sky," and Jim mentions it should have been the theme from "2001." In real life, the crew actually did play the theme from "2001." In this case, the film was joking about altering history for artistic purposes.
