The Day the Earth Stood Still (1951)

Visible crew/equipment: When Gort picks up Patricia Neal next to the flying saucer, you can see cables leading down to her body to keep her hoisted. (01:20:15)

Klaatu: I'm worried about Gort. I'm afraid of what he might do if anything should happen to me.
Helen: Gort? But he's a robot. Without you, what could he do?
Klaatu: There's no limit to what he could do. He could destroy the Earth.

Trivia: In order to make Gort's body appear seamless, two different costumes were created, one that opened in the back for front shots and one that opened in the front for rear shots. Unfortunately, as someone has already pointed out on this site, it was sometimes rather difficult to co-ordinate which suit was needed for which shot and thus there are several times in the film where Gort's seams can be seen.
