The word is that hundreds of Criterion titles will be available on Hulu for free over the weekend. There are some very, very great films in that list — from Wages Of Fear (1953) to Kubrick’s The Killing (1956) to Le Cercle Rouge (1970) and beyond.
One I’d particularly recommend is Anthony Mann’s The Furies (1950) starring Barbara Stanwyck and Walter Huston (in his last role).
Beware: If you watch them for “free,” there will be commercials embedded. Better to pay the $8, and better than that just to get the discs!
