The Mothers-in-Law is an American sitcom featuring Eve Arden and Kaye Ballard as two women who were friends and next-door neighbors until their children's elopement made them in-laws.

Desi Arnaz, who produced and directed the show, appeared in four episodes as a matador named Raphael Delgado y de Acha III, whom the wives had called as a result of a wrong number, and became somewhat of a family friend.

When choosing the two lead roles, executive producer Desi Arnaz approached two longtime friends Eve Arden and Ann Sothern.

Both actresses had been friends of Arnaz and his former wife Lucille Ball since the 1930s while working at RKO Pictures and MGM.

Actress Kay Cole, who would later appear on Broadway in the original cast of A Chorus Line, portrayed the role of Suzie Hubbard in the unaired pilot; however, after the series was picked up, Cole was replaced by actress Deborah Walley who would remain with the series for its entire two-year run.

Despite being sandwiched between Walt Disney's Wonderful World of Color and Bonanza, the show never garnered the ratings NBC had hoped for.

All cast members agreed to do the second season for the same money except for Carmel, who was replaced with Richard Deacon.
