The Big Year: A Tale of Man, Nature, and a Fowl Obsession by Mark Obmascik is being made into a movie starring Owen Wilson, Dustin Hoffman, and Jack Black.
In 1998 three birders, Sandy Komito, Al Levantin and Greg Miller, chased Komito's record of 721 birds in North America. In the end Sandy Komito kept his record, listing an astonishing 745 birds. Many in the birding community believe this record may never be broken, as 1998 was one of the strongest El Niño years on record and many vagrant birds ended up in North America.
Whether Owen et al can match the on-screen presence of Hunter Valley birdos Mick, Steve, and others in Chasing Birds, is doubtful, but with that cast it should be funny. Hopefully it can maintain the humour/respect balance of the book.
