Continuity mistake: When Elvis is at the pool singing "you're so square baby I don't care" watch his guitar player Scotty Moore sitting behind him. They use two camera shots for the scene. In one shot he has sunglasses on, in the other shot they are gone. This happens throughout the entire song.
Continuity mistake: In one scene, Elvis Presley's prison uniform displays the number 6239, yet in another it becomes 6240.
Audio problem: In one of his most famous movie scenes, Elvis lip syncs the wrong words to Jailhouse Rock. Watch his lips when he sings the words "The (band) was jumpin' down, the joint began to swing." (01:05:00)
Suggested correction: The correct lyrics are: "The band was jumpin' and the joint began to swing." Not sure if this corrects the lip syncing discrepancy though.
Factual error: When Vince Edwards is marking months off the calendar he marks months off on two consecutive years that have the same days of the week. That never happens.
