Following the overwhelming success of the Barbie movie, toy brand Mattel has begun work on an American Girl Doll Movie which aims to recapture a bit of that cinematic magic. Originally debuting in 1986, the American Girl Doll line features dolls of varying races, religions, and backgrounds, and places them at specific points in American history. Mattel purchased the brand in 1998 and immediately set about making American Girl a multimedia franchise similar to their Barbie products.
