After Tony makes a quick change from Smythe back to his Air Force uniform, he comes downstairs wearing a black shoe on his left foot and a brown shoe on his right. In the closeup shot (that Bellows sees) of his feet, he suddenly has a silver or grey boot on his right foot. In the next shot as he leaves the stairs the brown shoe is once again on the right foot.
When Dr Bellows is on the couch, the pillow behind his head is orange in the wide shot. But, the closeups show either an orange pillow or a green one.
Dr Bellows is certain that Geoffrey Tiffin-Smythe and Major Nelson are the same person. He calls for the British Officer to come downstairs. A split screen shot shows the two: Tiffin-Smythe on the stairs while Nelson beside Dr Bellows. However, Dr Bellows fingers fade as Hayden
Rorke's hand crosses into the other frame. Normally,
the final product would show his fingers cut off. Interesting sidebar: Larry Hagman is seen staring at Rorke's hand in that brief moment.
