Seth Green on mission to 'Mars'

Joan Cusack co-stars in Robert Zemeckis' film

Seth Green will star in Walt Disney Pictures' "Mars Needs Moms," Disney and Robert Zemeckis' ImageMovers' adaptation of the Berkeley Breathed children's novel.

Simon Wells is directing the performance-capture movie, which follows a boy named Milo who stows away aboard a spaceship to rescue his mom after she was kidnapped by aliens. Green is playing Milo.

The project reunites Green with his "Austin Powers" mom, Mindy Sterling, who will play the alien leader of Mars, inspiring terror in all who meet her. Dan Fogler ("Fanboys") is playing Gribble, a friend of Milo, and Joan Cusack ("Confessions of a Shopaholic") plays the mom.

Zemeckis, Jack Rapke and Steve Starkey are producing; Steven J. Boyd will executive produce.

Simon and Wendy Wells adapted the screenplay

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

Green, who continues to co-direct and write "Robot Chicken," the Emmy-winning stop-motion series he co-created with Matthew Senreich, next appears in Disney and Tapestry's comedy "Old Dogs" with Robin Williams and John Travolta. He is repped by UTA and Koopman Management.
