Factual error: When Henry is telling Albert to come to group, the baseball game on TV is starting. We see it's a game taking place at Yankee Stadium in New York City, which is in the same time zone as Trenton, New Jersey, where the hospital is located. However, the clock on the wall says 10:30. No major league baseball games ever start at that time.
Visible crew/equipment: When Billy is in the van telling the Wolf story, a microphone is visible behind Henry's left arm.
Revealing mistake: When Henry hits one of the corrupt cops in the head with an otoscope it bends off his head like rubber.
