- Listening to the real Marilyn Lovell choke up in the audio commentary as they watch Apollo 13 launch in the movie. You get a real sense of just how much they love each other. As it turns out, Jim and Marilyn Lovell are one of two couples from Astronaut Group 2 that are still married as of 2017, the other being Frank and Susan Borman.
(Marilyn has refused to allow news crew equipment on her front lawn)Marilyn: If they have a problem with it, they can take it up with my husband! He'll be home on Friday!
- The solidarity and faith she shows in the face of horrible times:
Blanche Lovell: Are you scared?Susan Lovell: (nods)Blanche Lovell: Don't you worry. If they could get a washing machine to fly, my Jimmy could land it.
- And his mother's faith in him:
Jim: Well, that looks like Marilyn Lovell. But it can't be. She's not coming to the launch.Marilyn: I heard it was going to be a hell of a show.Jim: Now, who told you that?Marilyn: Some guy I know...Jim: (chuckling) You can't live without me...
- Shortly before the launch, Marilyn tells Jim that she's thinking about not going to the liftoff, making Jim say "You're gonna miss a hell of a show." Then, the night before liftoff, as the crew says their goodbyes to their families and loved ones, Jim sees Marilyn show up.
- In real life, "you can't live without me" was the first thing Jim said to Marilyn after he returned from the mission.
- Forty years later, the real Gene Kranz still gets choked up when talking about how proud he is of the men in mission control who helped bring Apollo 13 home safely.
- "Gentlemen, it's been a privilege flying with you."
- After the Lunar Module Aquarius is jettisoned, after doing so much more than anyone ever anticipated, they say "Farewell, Aquarius, and we thank you," and "She sure was a good ship." Doubly heartwarming since they was taken directly from the original flight logs.
- Things are looking bleak for the Lovell family throughout the trip home, but when Marilyn and daughter Barbara watch an interview in which Jim recalls one time when he was scared but made it through, saying "You never know what events will transpire to get you home," it helps reaffirm their faith in him.
- As Ken is working in the simulators trying to create a power-up procedure for the Command Module, an engineer asks him if he needs a break. Ken answers "If they don't get one, I don't get one."
- Lovell's eldest son is in class at a military prep school when the Command Module is in radio black out during re-entry. We see the seconds tick past on the wall clock and the fear in the boy's eyes as they watch the live TV coverage. Then his teacher's hand comes down on his shoulder. No words are spoken, but that one gesture is enough.
- During the Apollo 11 landing party, when Neil Armstrong's about to make his first steps. Jim who was watching Neil on TV, rouses the rest of the group to cheer him on.
- "And you, sir, are a steely-eyed missile man." The actual line is taken from an incident that happened with the Apollo 12 missionnote , but it really is a sweet moment when one of the mission control officers bestows this compliment, the highest praise in the space program, on the head of the support team that designed the adapter for the CO2 filter.
- The show of solidarity shown by the people of the world in hoping that the Apollo 13 crew gets home safely.
- The news reports of crowds of people gathered in Rome and at Jerusalem's Wailing Wall to pray for three men's safe return home.
