Ravenous (1999)

Factual error: The film takes place around 1830, but you can see a character using a Colt Navy 1851, which was made 21 years later actually.

Visible crew/equipment: When the characters walk through the snowy woods, just before reaching the cave, Colhoun kicks a patch of snow that seems to fold in half, as though it is a towel or blanket.

Factual error: The American Flags being flown have the 13 stripes and 50 state stars. This is 1847 so only 29 stars should be shown on the flags.

Knox: What are you cooking?
Ives: It's, uh... stew.
Knox: Need any help?
Ives: No, no, no. Perhaps later you might... contribute.

Colqhoun: I said no food. I didn't say there was nothing to eat.

Ives: It's not courage to resist me, Boyd. It's courage to accept me.

Question: What is the theme that is played at the end and during the credits?
