According to The Hollywood Reporter, Jason Alexander and Judith Light have joined Robert Cary's Ira and Abby: A Divorce Comedy, which also will feature cameos from Saturday Night Live vets Darrell Hammond and Chris Parnell.

Alexander plays Abby's therapist in the screwball comedy from writer-star Jennifer Westfeldt and producer Brad Zions of Breakout Pictures, the team behind the indie hit Kissing Jessica Stein. Light plays the mother of Ira (Chris Messina, Six Feet Under) opposite Robert Klein as Ira's dad. After a chain of infidelities among the characters, a climactic scene brings the parents of Abby (Fred Willard, Frances Conroy) and Ira and the impulsively wed couple together with their six therapists (including Alexander, Parnell and Peter Hirsch).
