After the phenomenal success of the Barbie franchise, Mattel Films is venturing into the world of storytelling once again, this time with the cherished American Girl doll line. In a groundbreaking collaboration, Paramount Pictures and Temple Hill, known for their work on Maze Runner and Twilight, are teaming up with Mattel to bring these beloved dolls to life on the big screen. Lindsey Anderson Beer, who recently directed 'Pet Sematary: Bloodlines,' will be at the helm, both writing and producing the highly anticipated feature.
