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)
Character mistake: As he takes the elevator for the garage, Magnum's hat gets caught in the elevator doors before the camera cuts away. It's all fine on his head when he gets out. (00:42:15)
Factual error: It is stated in the episode twice that Rod 'did time' in Camarillo, but Camarillo does not have a penitentiary, just a jail and (had at the time) a State mental hospital, neither compatible with his 18 months sentence for growing weed. (00:25:00)
Continuity mistake: When Stuart Margolin shows Magnum a photo of his kid, the photo in close-up is entirely different from the one that Magnum was supposedly looking at. (00:06:35)
Continuity mistake: During the chaotic fight at the end of the episode, the guns are all very close together in a close-up view used a few times, but in wider angles they are spread around much more, from the beginning. (00:45:05)
Continuity mistake: Rod's tackle on the baddie happens twice in two separate shots, and his left hand clings to different spots - the arm in the first, the torso in the next. (00:45:00)
Visible crew/equipment: On the roof of the building, Magnum shuts the door of TC's chopper saying "What are you gonna do? Land on him with your helicopter?" Inside the door's reflection, there's the filming crew. (00:40:50)
Continuity mistake: After Magnum's adventure with the change at the coffee pot, he comes back to Rod and the parole officer. When Rod puts his hand on the phone to prevent her from calling the narcs, Ms. Gordon has the receiver in her lap. New shot and it's up and she lowers it only then. (00:29:50)
Continuity mistake: Magnum and Rod are talking about what happened; Rod is having a smoke and denies growing pot again. In close-ups, Tom Selleck's head casts a shadow to his right, but in the wide angles the shadow is on the opposite shoulder. (00:25:40)
Continuity mistake: Rod tells Magnum the story of how he went into jail and his wife divorced him. He says that "it happens" and massages his temples. In the next shot the pose is similar but he is leaning with his forehead against the back of the hand. (00:25:30)
Continuity mistake: After the run-in with Dolphie Crenshaw's men, Magnum and TC are talking with Rick. When he says "Don't worry 'bout it" his arms are crossed the opposite way than in the previous shot. Mistakes of the same nature happens later, such as when Magnum explains why he owes Rod and Rick's hands go from opposite upper arms to joined together. (00:14:35)
Continuity mistake: Magnum tries to have TC accept the cheque, but he is adamant about 'cash and carry'. During this scene, Magnum is holding the box with his hand positioned at a level that switches between two heights as the angle changes. (00:08:40)
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)
Forty Years from Sand Island - S3-E17
Revealing mistake: When Higgins' wheelchair starts taking off and he cries "I say, MAGNUM!" you can see rise from the grass a thin line used to safely halt the chair when off camera. (00:28:05)
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
Continuity mistake: For the greater part of the air duel, the jet of the bad guys has one window, but in the landing and in other shots it has two windows. (00:45:40)
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)
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
Factual error: When Sam climbs on the plane to give chase to the baddies, the tail number is N64CE. When he takes off though, the control tower announces the clearance for "Sixty-four Charlie Lima." Should have been Charlie Echo. (00:41:35 - 00:42:30)
Two Birds of a Feather - S3-E19
Factual error: No matter how good of a pilot Samuel is, he's chasing a Learjet 24 plane with a WWII design P-51 Mustang (that he does not even know how to start, but of course fictional pilots can just 'wing it' and do amazingly). Assuming that speed is not a factor since the bad guy is not flying at top speed just yet (but still he has a projected arrival time of 6 hours, meaning he'd fly around 700 kmh), they do the chase at high altitude (42,000 feet are mentioned), with Samuel not wearing a mask or anything in a non-pressurized plane! He'd have passed out.
