The Courtship of Eddie's Father
In 1969, Bixby starred in his second high-profile television role, as Tom Corbett in The Courtship of Eddie's Father, a comedy drama on ABC. The series concerned a widowed father raising a young son, managing a major syndicated magazine, and at the same time trying to re-enter the dating scene. This series was in the vein of other 1960s and 1970s sitcoms that dealt with widowerhood, such as The Andy Griffith Show and My Three Sons. Eddie was played by novice actor Brandon Cruz. Cruz and Bixby developed a close rapport that translated to an off-camera friendship as well. According to Bixby, "The amazing thing is that when we're working in a scene together, there's never a thought of conscious acting. Our natural affection for one another is what appeals to the audience." The core cast was rounded out by Academy Award-winning actress Miyoshi Umeki, who played the role of Tom's housekeeper, Mrs. Livingston; James Komack (one of the series' producers) as Norman Tinker, Tom's pseudo-hippie, quirky photographer; and actress Kristina Holland as Tom's secretary, Tina. One episode of the series co-starred Bixby's future wife, Brenda Benet, as one of Tom's girlfriends.
Bixby was nominated for the Emmy Award for Lead Actor in a Comedy Series in 1971. The following year, he won the Parents Without Partners Exemplary Service Award for 1972.
Bixby made his directorial debut on the sitcom in 1970, directing eight episodes. ABC cancelled the sitcom in 1972 at the end of season three.
According to Bixby, his experiences on The Courtship of Eddie's Father helped make him ready for marriage and fatherhood.
After the show was cancelled, Bixby and Cruz remained in contact, with Cruz making a guest appearance on Bixby's later series, The Incredible Hulk. The death of Bixby's only child, in 1981, drew Bixby and Cruz closer still. The two remained in contact until Bixby's death in 1993. In 1995, Cruz named his own son Lincoln Bixby Cruz.
Brandon Cruz said of the show that developed a professional father–son relationship, compared to that of The Andy Griffith Show, "We dealt with issues that were talked about, but were never brought up on television. Bill wasn't the first actor to portray a single widowed father, but he became one of the popular ones, because of his easy-going way of this crazy little kid." Prior to Bixby's promotion to director, Cruz said, "He was looking for the best dolly grip, along with the boom operator that if something was called specifically and failed, Bill could be easily angry." On the kind of relationship Bixby had wanted with his co-star, Cruz also said, "Bill would never speak down to me. Bill treated me as an equal. He made sure that we had a lot of time together, just so he could kinda crawl inside my head and see what actually made a kid tick." Upon the death of Bixby's real-life father in 1971, Cruz stated, "He had that type of mentality that the show must go on, thinking it was just a great TV show, after he broke down weeping."
In a 2011 interview with Marilyn Beck and Stacy Jenel Smith about how Bill Bixby's fame was supposed to posthumously honor him for a star on the Hollywood Walk of Fame, Cruz said, "When I found out they were putting this out, I thought, 'It's about time.' Bill Bixby had an amazing body of work, not only Courtship of Eddie's Father, but My Favorite Martian, The Magician, The Incredible Hulk, and so many other things, as an actor, as a director — and he never got an Emmy. He's never been recognized posthumously by the Academy. And he doesn't have a star on the Hollywood Walk of Fame. That is criminal.... There are people who have stars that, not to be blunt, but I wouldn't bother spitting on their stars. Bill's talent would take a couple of blocks of stars compared to them. It really demeans the whole thing that Bill is not included."
