The Paper Bag Princess by Mr. Robert Munsch and Illustrated by Michael Marthenko would be made into a movie by Universal Pictures. The plan is to have Ms. Elizabeth Banks to direct the live-action movie adaptation. Ms. Katie Silberman would pen it and Ms. Sara Scott, Universal's VP Production, would oversee it. Ms. Banks and Mr. Handelman is producing the feature along with Ms. Robbie and Mr. Ackerley for LuckyChap Entertainment, Mr. Krech and Mr. Unkeless( Clubhouse Pictures).
The book has been adapted before, but in animation only. It was part of the animated series Bunch of Munsch. Here is the Youtube read-aloud for The Paperbag Princess: (BTW, I do not own this youtube clip)
