When "Fish" is flung off the top of Vesuvius' van he lands with his head towards the van, but in the next shot he is sideways.
Vesuvius is booed off the stage and the crowd chants for ADD, they get back on stage only a minute after Vesuvius walks off but the drum kits have changed from Vesuvius's kit to ADD's. It's impossible to do this in a minute and the road crew had no idea they were coming back out.
During a crane shot of the Rock and Roll Hall of Fame show Fish's drum set appears as a larger drum set with two bass drums instead of the smaller setup with just one bass drum with "A.D.D." written on it.
When the band is recording "Bitter", the position of Curtis's microphone changes throughout the song, from up near his face, to down by his chest.
During the montage scene, before the band watches their music video, Fish high fives Curtis and you can see that his hair has already been cut short.
YouTube does not allow you to upload videos with nudity in them (the video of Robert naked).
Vesuvius is slated to be inducted into the Rock and Roll Hall of Fame after 20 years together. However, artists aren't eligible for induction (barring an extenuating circumstance) until 25 years have passed since the artist released his/her/their debut.
When the video director asks the band to read the words backwards, he has a sign held up for them to read backwards words. However, the word 'mistake' is spelled as k-a-t-e-s-i-m when it should be e-k-a-t-s-i-m. If you sound out "k-a-t-e-s-i-m" phonetically, it would be "mistake" backwards. "e-k-a-t-s-i-m" wouldn't work.
When "Fish" is flung off the top of Vesuvius' van you can see he lands on a mat.
When Amelia and Matt are playing Rock Band on the tour bus, the notes continue to be hit on the TV after they stop playing the Rock Band guitars to talk, and it switches from one player to two between shots.
After Aziz has taken off the plastic wrapping of his new bought Vesuvius CD, he takes it out the box and holds it up with the back facing the camera - The CD is clearly a CD-R with a green recordable back, not a silver backing like any original store bought audio CD would have.
In almost all cases, where a band member leaves, they would still get residual royalties from any albums/songs that they took part in the recordings or they would be paid a lump sum from the band as a buy out. So Fish should have had some money stashed away when he was kicked out of the band.
During the concert at the Q (Quicken) Arena, toward the end of ADD's first song the cameras pull back for a "balcony shot" and Curt and Amelia are suddenly LEFT HANDED. This is not a "mirror" shot because Amelia is still stage right and Matt is still stage left in relation to Fish the drummer.
When Curtis asks Fish why he wouldn't want to play The Q (Quicken Loans Arena) Fish says he "saw Ozzy bite the head off a bat on that stage" but that famous bat incident happened Jan. 20, 1982, in Des Moines, Iowa. The Q is in Cleveland, Ohio and wasn't built until 1994 when it was known as The Gund Arena.
During shots of the Rock and Roll Hall of Fame show the tom drums appear loosened and out of tune and would not produce the sounds heard live.
When A.D.D. first gets on the bus, Gator makes a reference to "heading north on the 5." They were in Cleveland, but the 5 is on the west coast. Also, north from Cleveland gets you very wet.
When Fish is on the porch he looks at the Rock Hall. There is no such view from any house in Cleveland. The Rock Hall is downtown, surrounded by large buildings with no residential neighborhoods.
When Fish is kissing the mom on the roof on the Midwest Tour, the Toronto skyline (Bank of Montreal Tower, Scotiabank Plaza, and TD Tower) is in the background.
The skyline shown right before A.D.D. views their music video is of Minneapolis (Wells Fargo building, US Bank building, etc.) not Cleveland.
When the Taxi carrying Fish pulls up in front of Mr. Lee's Restaurant, a 416 Area Code (Toronto) is visible on a sign, as well as the word Toronto on another sign. This row of businesses is in Chinatown, on Spadina Ave.
Matt comes to Lee's basement to present Fish with a laptop and web-cam to practice, but Matt wouldn't know where Fish was staying as Matt was grounded so could not use the phone, Fish is not seen to own a phone and Matt's mum would not want to stay in contact with Fish.
When Fish takes the phone photo with Curtis, he says "on three", but then starts counting down "three, two, one."
