Former Seinfeld stars Jason Alexander and Michael Richards are to reunite on actress Kirstie Alley's new TV sitcom. The new show, Kirstie, will also bring another classic TV pairing - Alley's Cheers co-star Rhea Perlman is also among the cast. Announcing the casting news on Thursday (13Jun13), Alexander says, "It is a strange and wonderful thing to be working on a brand new show yet surrounded by familiar faces and friends. I'm looking forward to a fun and fabulous time." Alley will play Broadway star Madison Banks in the new TV comedy.
