Was Steven Cannell a big fan of this movie?
In this movie, Marlowe (James Garner) gets Winslow (Bruce Lee) to leap at him and fall to his death by implying that he's gay. In the pilot of "The Rockford Files", Jim Rockford (Garner, again) insults a thug (William Smith) by implying that he's gay in order to get him to slip in some soap on the floor and knocking him out.
In the movie, Marlowe asks a thug who's beating him up "Does your mother know what you do for a living?". In the first episode of "…Rockford…", "The Kirkoff Case", a gang of thugs are working Jim over and he asks the head thug "Does your mother know what you do for a living?".
This movie has a gangster named Sonny Steelgrave (played by H.M. Wynant). On "Wiseguy", it's most memorable villain was named Sonny Steelgrave (played by the late Ray Sharkey). If Cannell wasn't a big fan, he certainly liked Marlowe a lot.
