Factual error: This is a wardrobe error... in the next morning scene after William has been deflowered, he is still in his Fruit of the Looms, which have the name printed on the elastic waistband. Fruit of the Loom did not print their name on waistbands like this until the 90s, in the 70s they just had single blue and yellow stripes. (01:08:27)
Continuity mistake: In the scene where William is sitting in the tub working on his notes, after Penny comes in and sits on the toilet, he scrambles out of the tub and most of the notes which were on the side of the tub fall on the floor. In the next cut when the camera is positioned near the bathroom door, looking in, all of the notes are back on the side of the tub and none are on the floor.
Other mistake: When Russell Hammond goes to William's house he spots a professional photo of William and his sister Anita. The photo shows William as a 15 year old with his sister. But Anita has been away working as a stewardess, and has not seen William since he was 11 - who was played by a younger and different actor in those scenes.hcherri1
Continuity mistake: Backstage at the first concert, William is sitting alone writing when Penny comes to talk to him. She has her glasses in her hand as she frames his face to guess his age. As the scene is shown from different angles, she is shown both with the glasses in her hand and without them in her hand depending on the shot.
Factual error: When William runs into the street to look for Penny Lane, he runs between a row of taxi cabs. Across the street is a blue mid 90's model GMC Suburban. Since the scene takes place in 1973, this is obviously a mistake. It may be necessary to use zoom, depending on the size of your screen. (01:28:10)
Continuity mistake: In the scene where Russell jumps off the roof into the pool, you can see that two people from the top left corner jump into the water to save him; then in the next shot you can see that no one has jumped in because the surface of the water is undisturbed and then the same people jump in again.
Continuity mistake: Right after the scene in which the band has a fight over the T shirts, which Dick says is the band's first T shirt, you see Russell and William go to a house party in Topeka. One of the attendants of the party has a Stillwater shirt that is of a different design than the shirt first revealed at the show only minutes prior, which again was supposedly their first shirt. The shirt seen on the partygoer can also be seen later in the movie.
Audio problem: When the band is in the limo coming into NYC, Jimmy Fallon gives the band a quick pep talk (e.g., "all you can do is be yourself and leave a pint of blood on the stage"). When the shot changes from inside the limo to outside the limo, the audio does not match the movements of Jimmy Fallon's mouth.JW Pepper
Continuity mistake: During the scene when the entire group are singing 'Tiny Dancer' on the bus, William cuts Penny off just as she opens her mouth to sing the next line, however the audio of everybody else singing doesn't start that line for another 3-4 beats after Penny opened her mouth.
Continuity mistake: In the poker scene where Russell loses and has to trade Penny for a case of Heineken, Russell gets up to talk to William. Russell brushes his hair behind his ears, and in the next shot, his hair is down again. His hair goes back and forth the entire scene.
Factual error: When the band is heading to New York City, there is a scene of them driving over a bridge heading into New York. In the background, you can very clearly see the Citicorp Centre Building. While the movie takes place in 1973, Citicorp Centre was not built until 1978.
Continuity mistake: In the scene where Russell and Jeff are arguing about the band's T-shirt their manager is standing behind Jeff, but when Jeff says that Russell " allowed Dick to manage us" Dick is sitting on the couch. At the end of the fight, the manager is standing behind Jeff again.
