Zach Galifianakis has had a great fall. Following his big splash with summer's $461 million grosser "The Hangover," Galifianakis has scooped up a batch of film roles. Now, he's entered negotiations to voice the Humpty Dumpty character in "Shrek" spinoff "
Puss in Boots."
Tom Wheeler is writing the screenplay for the prequel, which will feature the voices of Antonio Banderas and Salma Hayek in a story about the events leading up to the feline assassin's first meeting with Shrek & Co. in the second film.
