Revealing mistake: At the King Kamehameha Club, while Joan Gibson is sitting at the table, there are at least two wires crudely attached to the bottom of the tablecloth preventing the wind from blowing it upward, and disrupting filming of the outdoor scene.
Revealing mistake: Magnum just set foot in the bar, and finds TC and Rick there. Buck puts the crutch against the back of the couch, but it won't stay still, so Darren McGavin tries again. This time, a stagehand just out of frame catches it and draws it out of frame. (00:19:40)
Revealing mistake: When he trades some punches with the big guy in the bar in a fast paced sequence, back to the camera, "TC" is a good 20 pounds lighter. (00:23:05)
