Fans of Buddy Ebsen and William Shatner did not have to wait long to see them working together again. Ebsen and Shatner were reunited in the television movie The Horror at 37,000 Feet (1973), which was broadcast on February 13, 1973, a mere nine days after "To Catch a Dead Man." This also featured Darleen Carr, who plays Barnaby's client.
When Barnaby is at the veterinarian's office, he tells the receptionist that he doesn't have a pet; however, in the next episode, "Sunday: Doomsday," he has a dog named Chase.
Stuart Nisbet makes his first of six appearances on Barnaby Jones.
William Shatner and Lee Meriwether earlier co-starred together in the Star Trek episode That Which Survives (1969).
