Continuity: Toward the end where the guitarist comes to talk to the kid at his house. He turns the chair around to sit in it backwards, but throws the shirt down onto the ground. When he sits down the shirt is back on the chair.

Factual error: The airplane that Penny Lane is on has small vertical stabilizers on the wingtips, which were not designed into commercial jets until the early 90's.

Factual error: It's 1969 and William Miller is looking through a bunch of very awesome vinyl records that his sister has given him, including stuff from Cream, Jimi Hendrix, and Bob Dylan. In the stash is Joni Mitchell's Blue. This is a mistake, since Blue did not come out until 1971.

Continuity: When Russell and William are walking together to "find something real" the VW bus containing the "real Topeka people" drives by behind them 2 times over their left shoulder before pulling up to them a third time on the right side.

Other: Penny Lane picks up William to go see Stillwater at the Riot Club in L.A.  In the very beginning of the scene in her car, a reflection passes up the windshield over William's face as they are driving.  The Reflection is the prism and spectrum from Pink Floyd's "Dark Side of the Moon" album.  There are no other reflections in this scene.

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.

Continuity: 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.

Factual error: In the radio station scene, the closeup of the turntable tonearm shows a P mount head-shell and Stanton 500 cartridge. Neither was available until the mid 1980s.

Continuity: When William and Lester are talking in the coffee shop, William is taking notes and writes "Dont make friends w/rock stars. Righteously DUMB. Industry of COOL". Lester never mentioned anything about anyone being "righteously dumb". The internet suggests a couple of lines have been cut; "'Cause they are trying to buy respectability for a form that is gloriously And righteously dumb. Now, you're smart enough to know that. And the day it ceases to be dumb is the day that it ceases to be real, right?"

Continuity: In the scene where the man 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: In the scene where William first meets the Bandaids, Black Sabbath comes around in a limo and a couple of the Bandaids touch the windows while they drive around to go down the ramp. Then another shot shows the Bandaids look at the car go around them again.

Continuity: 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.

Continuity: After Russell gets William into his first concert, his rectangular backstage pass is pasted to his left shoulder. Penny Lane shows up with a round backstage pass, and by the time the camera's back on William, the shoulder pass has disappeared.

Continuity: In the closing scenes, there is a shot of William waving goodbye to Russel outside his house. This must have been shot at a different time to the rest of the film, since William is much chubbier.

Continuity: 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: 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.

Continuity: 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.

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: In the scene where Penny overdoses, she's wearing calf-high tan boots. She falls over on the couch and dances with William while wearing them. When the doctor rushes in and forces her to vomit in the tub, however, her boots are suddenly gone.
