Visible crew/equipment: When Molly walks into the "memory lane" tent at the carnival, four shots in we can see the reflection of a crewmember (moving dark silhouette) on the glass display beside the entrance. Then as Molly turns the crank and looks into the Mutoscope, in the wideshot we can see a crouching male crewmember hiding behind the case, at the left side of the screen.
Continuity mistake: When Molly is in space, alone, a man she knew is on the other side of a door that has a circular window in it. The man uses his finger to draw the words "HELP ME." When we first see the words, they are legible and about a third of the way below the top of the window, but the next time the words are much higher up and hard to read, and the third time they are now back to the original place.
