He never finds clues or actual evidence of anyone's guilt. Just kind of figures out who was motivated by what.
Now watching an oddly anti-Armenian episode I don't remember having ever seen before. Could it be a dig at Mannix starring Armenian-American Mike Conners? I doubt it.
John Saxon was offered the role of Kwai Chang Caine on Kung Fu. He turned it down and it went to David Carradine. Saxon knew the story---that the role was supposed to go to Bruce Lee, but the network didn't want a show starring a Chinese guy---a "yellow man", they called him, according to Mako.
Bruce Lee was in the movie Marlowe starring James Garner as Philip Marlowe. Garner uses the same ploy on Lee that he uses against a karate guy in an episode of The Rockford Files. Accuses him of homosexuality so that he becomes enraged and throws a kick and----well, I don't want to ruin it for you.
Garner mentioned in a long interview available on YouTube that another private eye show was stealing storylines from The Rockford Files until they went over and told them to knock it off. He wouldn't say what the show was, but it must have been Simon and Simon----I watched it when it was on and noticed that they swiped a storyline.
Silly to plagiarize a current show. Always steal from an obscure source.
Lee H. Montgomery as "Cricket"
Of course, Charlies Angels and The Mod Squad were both Aaron Spelling productions.
