River of No Return (1954)

Continuity mistake: When Marilyn Monroe tries to untie the raft and Robert Mitchum can just catch the rope it the river flows from left to right. Later, when they take off again together, the river flows from right to left.

Trivia: Marilyn Monroe suffered a torn ankle ligament August 13th when she fell into the river during filming. She was rescued by Mitchum and a dozen crew members, and had a limp for several days.

Kay Weston: This country is crawling with Indians, and you're going fishing.
Matt Calder: There are lots of ways to die. Starving to death isn't my favorite.

Kay Weston: I supposed you never made a mistake.

Kay Weston: One thing about this, the longer you last the less you care.

Question: At the end how long is it between the time Kay goes into the saloon until Matt comes to take her "home"?
