This is a 35mm presenatation.
Chicago Reader review:
Tony hipster Wes Anderson (The Royal Tenenbaums) takes a left turn into stop-motion animation with this 2009 adaptation of the Roald Dahl children's book, and the result is an instant classic. The material allows Anderson to neutralize the most irritating aspects of his work (the precociousness, the sense of white-bread privilege) and maximize the most endearing (the comic timing, the dollhouse ordering of invented worlds). Like the rest of his movies, this one is essentially infantile—but when you're telling the story of a ne'er-do-well fox conspiring against a trio of nasty farmers, who cares? Noah Baumbach (The Squid and the Whale) collaborated with Anderson on the script; among the voice talents are Bill Murray, Meryl Streep, Michael Gambon, Willem Dafoe, and George Clooney, perfect as the roguish hero.
Here (and above) is the trailer.
