DreamWorks have managed to secure the vocal talents of Leonardo DiCaprio to voice Jack Frost in their planned screen adaptation of The Guardians Of Childhood, a yet to be released graphic novel.

With Peter Ramsey set to direct, the story follows a group of fairytale characters (Santa, the Easter Bunny, Tooth Fairy and Jack Frost) battling an evil spirit planning to take over the world.

Written by Shrek's William Joyce you can see where the idea came from!

Expect the first book in 2011 and the movie in 2012.
