Revealing mistake: When Daniel is running from Johnny and his gang after the bathroom incident at the dance, there's a lot of fog outside. If you look at one of the trees in the background, you can see that all the fog is being puffed out from behind the tree - obviously a fog machine.

Trivia: Director Jason Reitman is the son of Ivan Reitman, director of the original "Ghostbusters" and "Ghostbusters II."

Visible crew/equipment: A reflector screen is visible on Hawkeye's sunglasses at the very end when Thor and a restrained Loki are returning, presumably, to Asgard. (02:06:10)
