Kareem Abdul-Jabbar (Credited as Lewis Alcindor) & Gail Goodrich make a cameo as college teammates to a player on the run. Kareem & Goodrich played at UCLA in the 1960's & both were in the NBA during their appearance on Mannix. Kareem's first acting job. He'd film "Game of Death" with Bruce Lee a year later, but due to Lee's death, "Game of Death" wasn't released until 1978.
The beach house Mannix visited looking for Cal was later used as the home of another private eye, Harry Orwell, in early episodes of Harry O (1973).
First and only acting role for Gail Goodrich.
