Continuity mistake: When Randall catches Mike and tells him that he has half an hour to put Boo in her door he also says the door will be in his station. Later we see that the door is on station 5. But on the first day Mike and Sully are working on station 5 and Randall is on station 6.
Continuity mistake: Waternoose grabs a scream can and starts releasing all the energy and the red line starts to go down. There are white lines over sections of the can.

In the very next shot, the red line has suddenly passed the white line.
