Looks Like Ray Has a Double as Well
Maybe it's my imagination, but check this out. In "Reign of Terror", Whit Bissell plays a French officer who is a double for General Kirk. But it looks to me like they slipped John Zaremba into a uniform as well.
At the 26:00 mark on the DVD (chapter 7), Querque vanishes as the Tunnel picks him up. A nearby guard turns to look at where he was, then runs into the prison. The lighting is lousy, and you only get a second or two, but take a close look at that guard. He shows up again at 39:02 (chapter 9), just after we cut away from the Dauphin's cell, but his face is partially obstructed in that scene.
Am I hallucinating (again!) or is Ray moonlighting?
