More from Otto Preminger's "River of No Return"
The indians swim through rapids toward the raft intent on killing the heroes.
Mitchum dispatches one but the other manages to board the raft and appears to lunge for Monroe's throat.
A moment later we see that it was not her throat he was after but her blouse, which he rips off. It seems that once aboard the raft--or perhaps all along--his thoughts turn to rape. So single minded is he that he fails to make even the most rudimentary attempt to prevent Mitchum from hurling him into the water.
Preminger demonstrates both the Indian's sub-human savagery and Marilyn Monroe's cleavage.
