Corrected entry: When Jason is at home watching TV after his outburst at the convention, he is flipping through TV channels and finds a repeat of Galaxy Quest. However, he reacts to seeing the show on the TV while we still hear the audio of a previous channel.
Corrected entry: In the beginning scene at the Galaxy Quest convention the crowd is clapping and shouting to see the actors but when they cut to the back of the audience you clearly see the audience are not clapping and shouting, or even moving yet, but the sound of the clapping and the shouting is still there.
Corrected entry: There must have been a scene deleted that deals with Fred Kwan smoking pot. The parts that support Fred's "activities" are that he is holding a large paper sack (maybe carrying snacks for when he gets the munchies or the pot itself) while signing autographs, on the spaceport, and on the planet while rolling the sphere back to the shuttle; Fred seemed VERY interested in getting something out of the vending machine as they were being sent to the ship; and last, and most obvious, is that Guy Flegman actually asks Fred if he is stoned when he comes up with the idea to transport the rock monster onto the ship.
Corrected entry: When Nesmith is taking his ride in the Limo to what he thinks is a fan-based appearance, he is given a can of Coca-Cola to drink. The can has the traditional white, vertical 'Coca-Cola' writing on an all-red can. The next scene of him on the space ship shows him drinking from the same can, yet it now has the special-edition black, white & silver, diagonal 'Coca-Cola' lettering on a metallic red can.
Corrected entry: If the Thermians studied the show enough to base their entire way of life upon it, shouldn't they freak out at seeing Guy alive and well despite him being killed in the "historical documents"?
Corrected entry: When Jason is fighting the pig creature, he leaps over it and rolls on the ground. He is wearing short sleeves, but the next shot of him shows that his arms are perfectly smooth and unscratched even though he took a pretty rough tumble in the sand.
Corrected entry: Nesmith is welcomed to the real, Thermian-created spaceship by Mathesar, who says, "Welcome to the 'Protector II'. However, when the ship is shown it is only christened with the name 'Protector'.
Corrected entry: When Sigourney Weaver and Tim Allen are trying to disarm the over-load/destruct sequence, there is a nice shot of the computer's timer showing the passing seconds counting down. The timer even has three decimal places, accurate to within 1/1000th of a second: pretty precise timing, to be sure. The computer also 'speaks' the countdown as the numbers are shown counting down, but for the entire countdown, the computer doesn't even come close to matching the digital display shown. The computer states "one second" when the display shows "1:999" which is of course basically two seconds. Pretty sloppy accuracy for such a sophisticated device.
Corrected entry: Nobody knows Guy's last name prior to the end of the movie, yet Jason calls him Fleegman when they are planning to steal the beryllium sphere from the mine. Jason did NOT know Guy's last name prior to this operation, as Guy asked everyone what his last name was while in the transport pod and nobody answered, leaving Gwen to comfort him with, "Guy, you have a last name."
Corrected entry: Just after Sarris has sent his first missile at the ship, Guy says, "Uh, guys, there's a red thingy moving towards the green thingy." The display on Guy's radar screen changes between shots of Guy (a large spherical diagram) and the close-up of the screen (lines and dots).
Corrected entry: When Gwen and Jason are going through the chompers they are shouting "Go" and "Stop" etc. However, when you can see their mouths, they are not in sync with the audio.
Corrected entry: There is no way that the alien who shot Quelleck could have done so from the angle shown - the aliens' bullets do not bounce off walls, therefore he would have had to have been behind Quelleck, but he was down the corridor.
Corrected entry: The amount of time that gets reset when Taggert presses the Omega 13 is a LOT longer than 13 seconds.
Corrected entry: When the two guards are thrown into the air lock, the last one does a voluntary leap through the open door which looks very unconvincing.
Corrected entry: Considering the pains the aliens went through to reconstruct the ship, why do the chompers vary in speed so much from the TV show to the real ship?
Corrected entry: The ship was built using the idea and the functions of the original Galaxy Quest show's ship. On the original Galaxy Quest show, they used "beryllium spheres" to run the ship. So, how would it be that there is a planet with these "alien miners" that actually make these spheres if the idea of the spheres came from a television show.Lisa DesGroseilliers
Corrected entry: Near the end, there is a scene where the Commander and the Advisor are pretending to fight in front of the aliens. They start calling each other names. After, the Commander comments that the Advisor called him a raving egomaniac. But he never called him that. What he actually said was "raving lunatic."
