Detroit Rock City (1999) - 6 major mistakes

Factual error: In the scene where Mystery is playing "Rock & Roll All Nite" in the basement, Hawk is playing an Epiphone Special II guitar. The movie is set in 1978, and this guitar did not hit the market until 1996.

Continuity: When Hawk is drinking the Bourbon on the rocks, the lemon wedge disappears when he spits out, and re-appears after the scene when the lady giggles.

Continuity: When Beth and Jam hit heads to pick up his drumstick, she is holding the stick in her right hand. Then next scene, she's rubbing her head with her right hand and holding the stick in her left hand. Then they go back to the original scene and she hands him the drumstick with her right hand.

Continuity: In the opening scene where Jam's mum is trying to listen to the record player, she shakes the shelf to try to turn it off, but there's a silver statue that keeps falling. It falls about 7 times in about 40 seconds.

Continuity: When the boys are in the car, the two boys in the back seat switch places. At first you can see Jam on the left, and then he is on the right.

Continuity: When Hawk is puking in the blender at the strip club, he fills it up, but when the bouncer takes the blender, it's only 3/4 of the way full.
