Seth Green, Joan Cusack Join Mars Needs Moms

ROBOT CHICKEN co-creator Seth Green has joined MARS NEEDS MOMS, from Disney and producer Robert Zemeckis' ImageMovers, according to THE HOLLYWOOD REPORTER.

Based on the Berkeley Breathed children's book, the story follows a boy named Milo (Green) who is a stowaway on a spaceship to rescue his mom from alien abductors. Green's AUSTIN POWERS mom Mindy Sterling will play the alien leader of Mars. Other voice cast announcements include Joan Cusack as Milo's mom and Dan Fogler as Gribble, a friend of Milo's.

Simon Wells will direct the motion-capture film, with Zemeckis, Jack Rapke and Steve Starkey to produce and Steven J. Boyd to exec produce. Simon and Wendy Wells are writing the script.

Green told the REPORTER that the mo-cap process was "performing in a black box theater with no costumes, no sets, just actors looking into each other's eyes trying to make it real."
