Shot in 1958.
Hilariously riffed by the former MST3K legends Mike, Bill & Kevin for Rifftrax.
At 29:58 there is an error in the English caption. The team photographer, referring to the film in his camera, says "... I'm taking a whole roll on this run...". The English caption incorrectly has "role" rather than "roll".
