There is a live action Frosty movie in development and they might cast Jason Mamoa as the snowman. A little girl named Karen and her friends build a snowman and name him Frosty. When a greedy magician's hat ends up landing on top of his head, Frosty's face moves and out from his mouth comes: "HAPPY BIRTHDAY!" The children play with Frosty, but it starts getting a little warm outside and unless he can reach the North Pole, Frosty is going to melt. Frosty and Karen take a ride to the North Pole, but Frosty jumps off the train because Karen is getting too cold and the magician is in pursuit to get his hat back.
