Revealing mistake: The man who gets kicked in the face and chest by the two wicked ladies inside the building is not Tom Selleck. (00:26:45)
Two Birds of a Feather - S3-E19
Revealing mistake: The plane is supposed to be completely out of fuel and simply gliding when it passes over Magnum's head, but you can see its propeller is spinning. (00:09:15)
Two Birds of a Feather - S3-E19
Revealing mistake: In the shot when the plane tips over the tidal pool rocks, look at the tail of the plane to see the cables used to send the model plane crashing. (00:09:20)
Two Birds of a Feather - S3-E19
Revealing mistake: Sam takes off from Van Nuys on his Super Stearman. We'll see him in Waco do all sort of acrobatics...but when he is first shown in the air right after talking with Richard Roundtree, you get a glimpse of another cockpit where the real pilot is, strapped with the safety belt that pokes in frame. (00:20:30)
Two Birds of a Feather - S3-E19
Revealing mistake: Higgins' spotlight gets turned off, not shattered by a bullet. (00:22:10)
Two Birds of a Feather - S3-E19
Revealing mistake: Sam arrives back home and he's greeted by his happy son and dog that run towards him...only, you can see at the bottom of the frame that the dog swerves to avoid him, to go to his handler, and couldn't care less about him. (00:22:50)
Two Birds of a Feather - S3-E19
Revealing mistake: The first shot of the bad guys asking to reroute from NY to Hawaii shows the plane with its license number mirrored. (00:42:15)
Two Birds of a Feather - S3-E19
Revealing mistake: When the airplane is shown from the front in flight (control tower saying "Squawk 0223 and ident"), the person standing in for Sato is wearing sunglasses, while Soon-Tek Oh is not. (00:42:50)
Revealing mistake: After the credits, Magnum's friend is checking out of the Honolulu Herald, which is running an article with Magnum's photo but the usual gibberish filler text contained in other similar props. (00:03:00)
Revealing mistake: The fight scene with Magnum and TC has several shots with the real Tom Selleck and Roger E. Mosley, but the wide angles have been shot with the usual leaner stunt doubles. Magnum's double's face can be seen distinctly as he swings for the first punch, and he will appear later in the episode, uncredited. (00:12:25)
Revealing mistake: The criminals have to get back inside the house because the cars for their getaway are "waist deep in mud", but they show no sign of having been anywhere near them; their shoes and bell bottom jeans are spotless. (00:22:35)
Revealing mistake: As everyone marches towards the happy ending of the episode, the Higgins lookalike that walks by Magnum at the airport looks in fact nothing like Higgins. (00:41:50)
Revealing mistake: In the classic ending of the episode, there's an obvious use of a dummy who falls in unnatural, stiff motion. (00:45:35)
