The Call of the Wild (1972)

Heston and his opposite are in 2 scenes, neither containing nudity, just partial undress in the one case and implied exposure in the other.

There is quite a bit of cruelty to animals, which is the most violent part of the movie until a gunfight at the end wherein several people are shot. Gore is minimal, as the fighting is in the dark.

Some profanity, a few obscenities.

The saloon is well liked........

The fight at the end is the most frightening, although there are some decidedly tense moments throughout.
