Apollo 13 (film) - Technical and Historical Accuracy

Technical and Historical Accuracy

The dialogue between ground control and the astronauts was taken verbatim from transcripts and recordings, with the exception of one of the taglines of the film, "Houston, we have a problem." (This quote was voted #50 on the list "AFI's 100 Years... 100 Movie Quotes".) According to the mission transcript, the actual words uttered by Jack Swigert were "I believe we've had a problem here." (talking over Haise, who had started "Ok, Houston"). Ground control responded by saying "This is Houston, say again please." Jim Lovell then repeated "Ah, Houston, we've had a problem."

The tagline "Failure is not an option", stated in the film by Gene Kranz, also became very popular, but was not taken from the historical transcripts. The following story relates the origin of the phrase, from an email by Apollo 13 Flight Dynamics Officer Jerry Bostick:

"As far as the expression 'Failure is not an option', you are correct that Kranz never used that term. In preparation for the movie, the script writers, Al Reinart and Bill Broyles, came down to Clear Lake to interview me on 'What are the people in Mission Control really like?' One of their questions was 'Weren't there times when everybody, or at least a few people, just panicked?' My answer was 'No, when bad things happened, we just calmly laid out all the options, and failure was not one of them. We never panicked, and we never gave up on finding a solution.' I immediately sensed that Bill Broyles wanted to leave and assumed that he was bored with the interview. Only months later did I learn that when they got in their car to leave, he started screaming, 'That's it! That's the tag line for the whole movie, Failure is not an option. Now we just have to figure out who to have say it.' Of course, they gave it to the Kranz character, and the rest is history."

A DVD commentary track, recorded by Jim and Marilyn Lovell and included with both the original and 10th-anniversary editions, mentions several inaccuracies included in the film, all done for reasons of artistic license:

"We were working and watching the controls during that time. Because we came in shallow, it took us longer coming through the atmosphere where we had ionization. And the other thing was that we were just slow in answering."

Apollo 13's four-minute re-entry into Earth's atmosphere

• In the film, Mattingly plays a key role in solving a power consumption problem that Apollo 13 was faced with as it approached re-entry. Lovell points out in his commentary that Mattingly was a composite of several astronauts and engineers—including Charles Duke (whose rubella led to Mattingly's grounding)—all of whom played a role in solving that problem.
• When Jack Swigert is getting ready to dock with the LM, a concerned NASA technician says: "If Swigert can't dock this thing, we don't have a mission." Lovell and Haise also seem worried. In his DVD commentary, the real Jim Lovell says that if Swigert had been unable to dock with the LM, he or Haise could have done it. He also says that Swigert was a well-trained Command Module pilot and that no one was really worried about whether he was up to the job, but he admitted that it made a nice sub-plot for the film.
• A scene set the night before the launch, showing the astronauts' family members saying their goodbyes while separated by a road, to reduce the possibility of any last-minute transmission of disease, depicted a tradition not begun until the Space Shuttle program.
• The film depicts Marilyn Lovell dropping her wedding ring down a shower drain. According to Jim Lovell, this did occur, but the drain trap caught the ring and his wife was able to retrieve it. Lovell has also confirmed that the scene in which his wife had a nightmare about him being "sucked through an open door of a spacecraft into outer space" also occurred, though he believes the nightmare was prompted by her seeing a scene in Marooned, a 1969 film they saw three months before Apollo 13 blasted off.
