The Big Year of 1998 was the subject of a book of the same name by Mark Obmascik. In that year three birders, Sandy Komito, Al Levantin and Greg Miller, chased Komito's record of 721 birds. In the end Sandy Komito kept the record, listing 745 birds plus 3 submitted in 1998 and later accepted by state committees for a revised total of 748. The book was adapted for the 2011 20th Century Fox film The Big Year.
As of 2011, the world record is still 748, but in the movie it is 755. Why is the record in the movie not the same as the real one?
