Season 3 of "The Comeback" premiered at SXSW, with co-creators Lisa Kudrow and Michael Patrick King discussing the show's focus on artificial intelligence. The audience was largely in agreement, with Kudrows saying that the character of Valerie Cherish, who has taken up podcasting after her two-season mystery series "Mrs. Hat," was sorely missed. The third season will premiere on HBO on March 22. New cast members include Jack O’Brien, Laura Silverman, and Damian Young. King and Kudrew said they found something worthy of “The Comereturn” coming back after 11 1/2 years.
