A perennial favorite of late-night cable TV:
RAIDERS OF THE LOST ARK
Archeologist "Indy" Jones (Jimmy Stewart) and his girlfriend Marion (June Allyson) and sidekick Sallah (Orson Welles) undertake a quest to find the Ark of The Covenant before the Nazis do. Directed by John Ford (under protest and contractual obligation), Raiders continues to be a fan-favorite despite it's obvious low-budget back-lot locations. The film does feature some innovative special effects work by Ray Harryhausen (although there is an obvious pane of glass separating Stewart from a snake in one scene). Look for some interesting supporting performances by Peter Lorre as the Gestapo Agent Major Toht, and Claude Raines as Indy's rival Dr. Belloq. Despite the film's age and flaws, many find it to be superior to Steven Spielberg's 1981 re-make starring Tom Selleck as Jones and Sean Young as Marion.
