Jacques Becker's "Le Trou" is one of the greatest of all prison-break films. No film lover should miss it. It is every bit as masterful and tense as other milestones of this subgenre, including John Sturges' "The Great Escape," Robert Bresson's masterpiece "A Man Escaped," and Don Siegel's "Escape from Alcatraz." The meticulous preparation for the escape is a nail-biter, with many adrenaline-inducing close calls. The ringer: Will the newly exonerated prisoner stay with the group and escape or rat on the others? Those seeking pure entertainment or those seeking existentialist philosophical fare will be equally pleased. A memorable movie experience.
