1) Cushman reads a source saying pick-up scene for "The Naked Time" was filmed during "The Man Trap".
2) Cushman sees Budd Albright in "The Man Trap", thinks it's Bruce Hyde and concludes this was the scene in question.
This is probably what happened. Take a look at this shot
in 'The Naked Time' and this shot
in 'The Man Trap.'
I'm convinced. Thank you!
Seeing those pictures makes all the difference.
