I've seen each Funny Games. Can't recall which I preferred. English was several years later, however. Would not want to watch back to back.
Why do director's remake their own films? I wouldn't. Original The Vanishing('89?--Spoorloos), far, far superior to remake.
For the Haneke fans! Try 71 Fragments of a Chronology of Chance, Benny's Video, and most importantly The Seventh Continent. Existential, man!
