When Bo Svenson's character is showing his prowess with a .357 Magnum, one of his shots is a bullseye, yet when they bring the target up to review it there isn't any shot through the bullseye.
When Lieutenant Frank Sirriani (Robert Culp) goes to Michael McBain (Bo Svenson)'s Judo dojo to speak to him, he is wearing a red tie. In the next shot, after having been directed downstairs to where McBain is giving a lesson, Sirriani is wearing a green tie.
