Factual error: Listening to a radio broadcast, live, since no other indication is given, Joe Louis is completing the 12th round of a fight. This is December 6, 1941. Joe's last fight of 1941 occurred in September, his next fight was January 1942. (00:00:10)
Visible crew/equipment: When C-3PO is on the conveyor belt, if you look in the reflection in his head you can see the camera crew.
Continuity mistake: At the Gator Motel, after Cledus and Bandit get part of the money, when Bandit starts crying about Frog and blows his nose into the money, there is a side shot showing a wad of bills in Bandit's shirt pocket before he actually puts the bills into his pocket in a following shot. (00:12:45)
Revealing mistake: When Carl is caddying for the priest during the bad weather, the wind is so strong that it is almost blowing them over but the trees are not moving in the background.
Visible crew/equipment: When Jake is in the bedroom with his wife (where he pours ice water on himself to calm down) you can see the top of some crew member's head in the foreground right below the camera lens.
Factual error: The sun can't rise out of the Pacific ocean when viewed from America, as seen when Danny is playing the clarinet. (00:01:20)
Continuity mistake: When Loretta Lynn is at the radio station asking why the disc jockey had lied to them about playing her record, you see the picture of her that they took at home. It is a completely different pose than the one that you saw them take a couple of scenes earlier. She is looking in a different direction and she is not smiling as much as she was when they took it.
Factual error: In scenes that take place in 1912 on the porch of the hotel you can sometimes see American flags in the background. The flags in the movie have 50 stars. The 50 star flag wasn't adopted until after 1959. (01:25:15)
Continuity mistake: The movie is supposed to have been filmed and taken place exclusively in Pasadena, TX, and MOST of it is. The trailer park that they live in, however, is NOT in Pasadena, or anywhere near there. There are several scenes where they show someone driving into the trailer park, and you can see mountains in the background. There aren't any mountains within hundreds of miles of Pasadena.
Visible crew/equipment: In the town in Idaho when General Zod and his crew first visit, watch when the boy's father (elevated by Zod's finger) falls to the ground. You can see the pad under the dirt when he hits it.
Continuity mistake: When the German NCO begins to walk up the sand dune he has a stick grenade in his right boot. Next shot half way up the dune, the grenade has changed boots.
