Could this be a star-studded year for Eli Stone, ABC’s sophomore drama about a do-good lawyer? has learned that Sigourney Weaver — who voiced the ship’s computer on Wall-E this summer and co-starred in Baby Mama — will make a guest appearance on the critically-lauded dramedy this fall. She’ll play a therapist who treats Eli (Jonny Lee Miller), according to an insider. Earlier this summer, the show scored a major casting coup by recruiting Katie Holmes to sing and dance in an episode this fall.
