- Mathesar's undiminished faith in Nesmith, despite being captured and tortured by Sarris, is so touching.Mathesar: (Sarris's men bring Jason and the others into the room where Mathesar is tied to a table) Commander, thank God you're alive. Now you will face justice, Sarris...
- Alexander finally uttering his catchphrase on his own accord, and meaning it.
- Tommy putting so much effort into "re-learning" how to fly the ship, when he's finally convinced that it matters.
- Fred convincing Guy that he's not the "throw-away extra guy".
- And even right before that; Guy's weakening voice and legs show he's still as terrified of his (perceived) fate as before, but Guy has decided to accept it to save the rest of the cast and crew.
- When the show gets rebooted, Guy becomes a Ascended Extra with a badass name to boot.
- On the alien planet, in a blink and you'll miss it moment, Jason shows that yes, he DOES know Guy's last name.
- At the end of the film, the team has had a Dynamic Entry into the side of a convention centre (thankfully not killing anyone), with Sarris finally dead and the fans ecstatic. Jason goes forward to bow, but then remembers that his team are there, and tells them to all come forth, as he feels that they equally deserve the applause. They gladly accept, at which point Jason kisses Gwen. Contrast to the beginning of the film, when they were almost all reluctant to be there, Jason was hogging the limelight, and Gwen couldn't stand him at all.
- And as a metatextual heartwarming moment, we have Tim Allen, Alan Rickman, Sigourney Weaver, Tony Shalhoub, Sam Rockwell, and Missi Pyle (Laliari), taking their bows, which is something film actors rarely get the opportunity to do on-screen.
- Brandon and his friends, and the way the movie treats them. These aren't useless, pathetic geeks wasting their lives in a juvenile fantasy; they're intelligent people with strong interpersonal friendships, who have an incredible amount of passion for a show that has been empirically proven to change lives and make people (aliens, in this case) believe in friendship, loyalty, courage, and a better future. It's a love letter to Trekkies and their devotion to the show. Hell, at one point, the fans save the day. And they save it solely because instead of just shrugging the whole thing off as just a stupid TV show, they connected with it on a deeply emotional level and created something wonderful.
Brandon: "I'm not some kind of brain case, okay? Of course I understand that it's all just a TV show, there's no ship—"Jason: Brandon. Brandon! It's all real.
- On a meta level, the exchange between Brandon and Jason just adds to this—because while the events portrayed in the show obviously didn't really happen, the themes and the emotion that went into it were real.
- One for the con scenes, take a good look at the crowds in each of the cons. The con has people of all walks of life there: Men, women, children, married people, single couples, cosplayers, and so many more. It would've been so easy to show the fans as a bunch of overweight, under-washed neckbeards, but they didn't. They instead showed us the truth, that fans come in all shapes and sizes.
- One of the reasons Patrick Stewart, before finding out it was an Affectionate Parody, didn't want to see the movie was because he thought it would mock Star Trek fans. Jonathan Frakes thankfully talked him into it.Stewart: I had originally not wanted to see [Galaxy Quest] because I heard that it was making fun of Star Trek and then Jonathan Frakes rang me up and said You must not miss this movie! See it on a Saturday night in a full theatre. And I did and of course I found it was brilliant. Brilliant.No one laughed louder or longer in the cinema than I did, but the idea that the ship was saved and all of our heroes in that movie were saved simply by the fact that there were fans who did understand the scientific principles on which the ship worked was absolutely wonderful. And it was both funny and also touching in that it paid tribute to the dedication of these fans.
- Jason experienced a sad, in-universe Creator Breakdown in the beginning of the movie, in which he angrily admits to Brandon that Galaxy Quest is a dumb television show, nothing more, nothing less. He spends the rest of the night drowning his sorrows over the dull reality of his fandom, and the fact he's a shadow of his once truly successful acting self (while probably thinking I Wish It Were Real). And then, the next day, Jason's faith in Galaxy Quest and his role's recognition gets restored more than ever. He gets to experience the real thing, created by an alien species, and despite being initially freaked out, he becomes genuinely excitable like a little kid, whose imagination turns into reality. Seriously, watch Jason blabbering to the other cast members about the ship. He's so damn thrilled experiencing the fiction becoming real, and getting to play his role again in a real space adventure.
- Just think: even the most cynical Hollywood hack would like to think that their words and ideas could inspire an entire civilization to better itself. The Thermians' loved Galaxy Quest so much, it gave them hope and inspiration even as Sarris was hell-bent on their genocide.
- Speaking of which: Despite starting out an egomaniac, Jason gets a Pet the Dog moment when he immediately decides to share his experience with his resentful co-stars, including an especially bitter Alexander Dane, in order to restore their faith in Galaxy Quest as well. Sure, they think he's full of it (especially after he lost some evidence to Brandon by mistake), but once they finally manage to get on the ship, they're awestruck. (Well, except Fred.)
- Also, Brandon was just about to accept Jason's initial tirade as a Jerkass Has a Point statement for Galaxy Quest just being a show to not get worked up on. That is, until Jason contacts him for his help out of the blue, and renews his faith by apologising for what he said to him earlier and saying it's all real. Brandon's response? "Oh my god. I Knew It!! I KNEW IT!!!"
- Despite disliking Jason's glory hound attitude, Gwen shows concern for him after witnessing his O.O.C. Is Serious Business Heroic BSoD Creator Breakdown when he lashes out at Brandon, after just losing faith in Galaxy Quest and himself.
- Not to mention that later on, in Gwen's phone call to Alexander, it's implied that Jason NEVER mistreats a fan and appreciates them greatly.
- It's also implied while the crew is arguing on the mining planet that Jason and Gwen had dated in the past.
- Earlier while trying to explain to the Thermians that Galaxy Quest is just a show, despite their resentment of their fandom that they grew over the years, especially Alexander, they tried to break it down to them gently without any mean-spiritness or flippant-ness that should be expected from actors who disliked being remembered for a certain show. Even when Sarris held them and Mathesar captive during their Darkest Hour, Jason became the most reluctant to break it down to the usually happy-go-lucky Mathesar, who then goes into a Heroic BSoD when realizing it.
- Nesmith's farewell to Mathesar:Mathesar: We were hoping you could come with us. You see, my people have no commander.
Nesmith: Mathesar, I think your people have a great commander, sir. (salutes him)
- Followed by Teb giving Mathesar an additional smiling salute.
- Laliari staying on Earth (and becoming a cast member on the rebooted show, which essentially makes her an Ascended Fangirl) because she and Fred have become an item.
- Theres not a word spoken when she and Fred approach Mathesar about her staying on Earth. They approach him, smiling, and he instantly understands and gives his approval. Jasons right, Mathesar is a great commander, putting the happiness of one of his crew first.
- After Jason defeats Sarris, he notices Brandon and his friends in front of the stage, and salutes them in recognition.
- When Mathesar explains how the "Historical Documents" helped shape their society:Mathesar: Yes, in the last hundred years our society had fallen into disarray. Our goals, our values had become scattered. But since the transmission we have modeled many aspects of our society from your example, and it has saved us. Your courage, teamwork, friendship through the adversity... In fact, all you see around you comes from the lessons garnered from the historical documents.''
