Heaven Knows, Mr. Allison

Terrific two-character WWII drama finds tough (but tender-hearted) Marine sergeant Allison (Mitchum) stranded with Irish nun, Sister Angela (Kerr), on a Pacific island overrun by Japanese troops. The duo hide out during the day and forage for food by night, gradually revealing their pasts to each other. He falls hard while she resists his advances and they struggle to stay alive until U.S. forces invade the island. Lots of action and good performances. Based on the novel by Charles Shaw.
