The Princess and the Frog screenwriter Rob Edwards has signed on to write two projects for Warner Bros., Amulet and An Animated American.

Amulet is based on the graphic novel by Kazu Kibuishi and follows teenage siblings who discover a world of demons and monsters. They come to realize that they are actually the last in the line of guardians who must keep these creatures at bay with the help of a mystical amulet. Will Smith and James Lassiter are producing Amulet through their Overbrook Entertainment banner. Both Will Smith and his son, Jaden Smith, were at one time attached to star, although it is not known if they are still attached.

An Animated American will be produced by Robert Zemeckis, Bob Cooper, and Dan Fogelman. The story centers on an animated baby who is raised by a live-action family until the age of 18, when he decides to find his real family.

Warner Bros. hasn't locked down a firm production date for either An Animated American or Amulet yet.
