Trivia

The trophy room scenes were much longer in the preview version of 78 minutes; there were more heads in jars. There was also an emaciated sailor, stuffed and mounted next to a tree where he was impaled by Zaroff's arrow, and another full-body figure stuffed, with the bodies of two of the hunting dogs mounted in a death grip. Preview audiences cringed and shuddered at the head in the bottle and the mounted heads, but when they saw the mounted figures and heard Zaroff's dialog describing in detail how each man had died, they began heading for the exit - so these shots disappeared.

The actor playing "Ivan the Cossack" was Noble Johnson, a multi-talented black American who was a childhood friend of Lon Chaney. This is the earliest known instance of a black actor playing a Caucasian character.

Jungle sets were also used for simultaneous filming of jungle scenes in King Kong (1933).

Some of the screams of the sailors as the ship sinks are the same as the screams of the sailors in King Kong (1933) when Kong shakes them off the log.

This film did well at the box office, earning RKO a profit $70,000 ($1,235,000 in 2016) according to studio records.
