The Brothers Brannagan
The Brothers Brannagan was a show about brothers Mike and Bob that investigate crimes using their detective skills. The show did not have much of an original premise, and so it didn’t thrill audiences. Despite appearances from actors like Ann McCrea, Christopher Dark, and Sterling Holloway, the show was cancelled after just one season.
Coronado 9
Coronado 9 starred Rod Cameron, which is why producers hoped that this show would do a lot better than it did. The show was about private investigator Dan Adams who solved cases using skills he accrued while in the Navy. The show lasted for just 39 episodes before it was cancelled.
