Smoking Gun - S1-E2
Continuity mistake: In the prologue, Young Murray finds a man he does not know sitting at a table. He advances towards him in a wide shot of the room, and the man positions his left hand on the corner of the table, but in the following closer angle on him, his hands are close together exactly like in the initial shot by the same angle. It's like the middle one never happened. (00:03:10)
