That would be truly chilling, if Martin, Fay Wray's drunk brother played by KING KONG icon Robert Armstrong, was shown going from a tipsy stooge to a frightened captor and then a hunted boar. Hopefully, Zaroff, who is extremely creepy, didn't turn him into Ned Beatty.
I agree that for today's audiences, that would be a powerful addition to the buildup of tension.
As I understand that part was filmed but cut after a preview.
They showed full-body stuffed victims in the pose of their capture. One guy nailed to a tree by an arrow, with two dead dogs at his feet. Audience members walked out at that point, so they cut it.
I think the sequence remains somewhere, but it wasn't in the version I just saw.
