Mr. October - S1-E2
Continuity mistake: Hermit and Bergerfeld interrupt a party to tell the people inside to evacuate the building. As Bergerfeld is trying to explain the situation to the man who opens the door, he has his hand up gesturing. The guy shuts the door in his face while Bergerfeld's hand is still up; the camera cuts to a different angle and suddenly his hand is down. (00:29:10)
