When Kate gives Angie a ride back to Kate's house/apartment, the outside scene shows a road sign for PA-51. PA Route 51 is a road in southwestern Pennsylvania, not a road near Philadephia, which is where the film is set.

When Mitchie and Shane Gray are singing "This is Me" at the end of final jam, about halfway through the song, Mitchie is heard singing the first verse in the background though her mouth is moving as if she was singing the chorus.

The shape of the crystal shard is all wrong. In a flashback scene a urSkek is seen "shattering" the original, pure crystal by hitting it with a rod on one of the crystal's flat surfaces. For argument's sake we will say that in their universe it would be possible for this to create a spear-shaped hole in the crystal. However, the top of the shard is a rounded surface; it should have a flat, slanted top to match the top of the hole it came out of. Could pieces have broken off the top of the shard to give it the rounded shape? If that were true the final solution would not have worked; only the whole, pure crystal would restore the urSkeks.

In the beginning of the film, when Pitka is using the voice-over machine, it is a black machine. In the bar scene however, the machine is a pale-ish orange color. The orange-ish machine is also used in the ending scene before the song.
