EXCLUSIVE: Diana Maria Riva and Spanish actress Claudia Bassols are set to co-star opposite Rob Schneider and Cheech Marin in the Schneider’s untitled CBS comedy, which is shooting a new pilot for midseason consideration as part of a recent order that also includes several backup scripts. The multi-camera comedy, which Schneider co-wrote with Lew Morton based on the actor’s real-life experience, stars Schneider as Rob, a confirmed bachelor who has just married into a tight-knit Mexican-American family. Bassols will play his wife Maggie and Riva his mother-in-law Rosa, roles played in the original pilot by Nadine Velazquez and Ada Maris, respectively. Riva’s age (she is younger than Schneider, who plays her son-in-law, and way younger than Marin, who plays her husband) suggests a possible trophy wife scenario. This completes the recasting of the CBS Studios/Tannenbaum Co. project, with new cast members Marin, Riva and Bassols joining pilot regulars Schneider, Eugenio Derbez as the wife’s uncle and Lupe Ontiveros as her grandmother. Bassols is a virually unknown in the U.S. but has has done a number of series in her native Spain. Riva, who recurred on Aaron Sorkin’s The West Wing and Studio 60, recently co-starred on the Fox dramedy The Good Guys.
