Other mistake: At the diner, J is given a strawberry rhubarb. For the first few seconds after being given his plate, he is never shown putting his fork in his food, yet he still chews anyway. (01:03:50)
Continuity mistake: At the diner, K asks J if he has a girl in the future. In that shot, J is looking down at his food. It cuts to a different angle and J is instantly looking straight forward as he is turning his head to K to say "I got you." (01:05:05)
Continuity mistake: When they arrive at the ball park, K gives J his stuff back. The close up of the time device in J's right hand shows his thumb is closed in close to his hand. But the shot cuts to show both him and K, and suddenly his thumb is stretched out. K also puts his arms down twice during this part. (01:06:10)
Continuity mistake: When Griffin places his arm back around J's shoulder after J steps back, J is shown to be looking at the baseball field. Next shot just as J says "So this is how you see things", J's head is suddenly slightly shifted to the left. (01:07:05)
Continuity mistake: When Griffin shows J and K the vision of the baseball game, J walks back and then walks back over to Griffin. Griffin then places his arm around J and his hand ends up around the top of his arm. In the next shot, Griffin's hand is suddenly on J's shoulder. (01:07:05)
Character mistake: Griffin states about the New York Mets saying "They were in last place every single season until they won it all". That is not true. They came last ever since they started in 1962 to 1967. In 1968, the year earlier, The New York Mets came second to last where as The Houston Astros came last. (01:07:30)
Continuity mistake: When K takes the prize out of the Crackers box, the size of the box magically becomes very tiny. (01:07:55)
Continuity mistake: When Griffin foresees the end of the baseball game his hands are on the J and K's backs, but a frame later he's grabbing their arms. (01:08:40)
Factual error: Just after Griffin finishes telling J and K that the Boglodites destroyed his planet, Boris appears on his motorcycle and snatches Griffin. J, K nor Griffin didn't see this coming whatsoever, until Boris appears. The main problem with this is that motorcycles have very loud engines, so whilst J, K and Griffin may not have seen Boris as they weren't looking at him, at least one of them should have definitely heard the sound of the loud engine coming from Boris' motorcycle. Plus, the sound from the game that Griffin was foreseeing wasn't even that loud so the cheering from the audience certainly wouldn't have intervened with anything. (01:09:00)
Plot hole: At the ball park stadium, K, J, and Griffin are high up in the bleachers watching a future window of the Mets game. Boris suddenly drives by on a motorcycle up in the stands and grabs Griffin, then plows through the railing on the side of the stadium and falls down below, crushing K's car. He then speeds off instantly out of the parking lot with Griffin. Then suddenly, somehow, J and K are running out into the parking lot close to their car quickly enough to be watching Boris speed away from the parking lot on the road. There is absolutely no way K and J could have made it out of the stadium and out into the parking lot in just a couple of seconds like that. (01:09:05)
Continuity mistake: When past and future Boris meet, past Boris turns towards future Boris completely and has his full body facing future Boris as he is walking toward him. But as future Boris is still walking towards past Boris and saying the line about spending the next 40 years in prison, past Boris suddenly has his body turned away from future Boris, and so future Boris has to step around in front of past Boris. (01:12:45)
Factual error: In the film, in 1969, prior to the launch of Apollo 11 the moon is shown to be a full moon, however, in reality, on the night before the launch the moon was a tiny crescent moon. (01:14:55)
Continuity mistake: As J is telling K the truth about Boris killing him at the Moon Launch, one shot from behind K shows his head is down. The next shot, he is suddenly looking straight forward as he punches J in the face. (01:16:15)
Continuity mistake: As Griffin is telling J that K has to go to the Apollo launch, the shot from his perspective shows J holding his nose from where K punched him, his hand being over his nose. The shot cuts to show Griffin's face and suddenly J is wiping the underside of his nose. (01:16:35)
Continuity mistake: As J is saying no jet packs, he has both arms out with his hands turned palm down. It cuts to a different angle saying there's a reason they don't have those in the future, and you can see his left hand. It is suddenly gesturing towards the machines but palm up. (01:18:40)
Continuity mistake: As O is helping K into the jet pack harness, he asks her if that is right. She says "Unfortunately it is." In that shot, she is looking up at him right into his eyes. It cuts to a side angle and she is suddenly looking at his mouth and chin. (01:19:15)
Continuity mistake: Before leaving in the jet packs to go to Cape Canaveral, O steps off K's jet pack twice between shots. (01:19:25)
Factual error: The flag of Spain shown at Cape Canaveral is not the official one used in 1969 but the one adopted in 1981. (01:19:50)
Factual error: Apollo CSM is venting something through RCS thrusters in the scene on the launchpad. It is not correct, because RCS works on aerozine (UDMH, hydrozine) that isn't cryogenic fuel. Also, video/photo from the actual launch doesn't show this venting: http://spaceflight.nasa.gov/gallery/images/apollo/apollo11/hires/s69_39525.jpg http://spaceflight.nasa.gov/gallery/images/apollo/apollo11/hires/s69_39961.jpg http://spaceflight.nasa.gov/gallery/images/apollo/apollo11/hires/s69_39962.jpg http://spaceflight.nasa.gov/gallery/images/apollo/apollo11/hires/s69-39529.jpg http://youtu.be/zGNryrsT7OI. (01:21:45 - 01:24:35)
Deliberate mistake: The Army Colonel's Class A uniform does not have a name plate on the flap of the right breast pocket as per regulations. If the Colonel's name plate was present, there would be no twist to the movie. (01:21:50)
Chosen answer: The gold saucer crashed in middle of the street was the ship Boris stole to get to earth. While they are in the restaurant Kay gets a call that tells him a ship was taken from lunar max and it was Boris who took it.
