Continuity mistake: Magnum gets out for a swim after the second sleepless night, carrying just a towel. He has a run-in with the lads, and spends all the time running away from them till Mac fetches him and they get back to the guest house. Magnum is now also wearing his Detroit Tigers cap and brought no towel back. (00:42:15 - 00:43:45)
Continuity mistake: When Magnum's wife is praying in the chapel, the Virgin Mary statue bare casts a shadow on the right part of the corner in close-up, while in wider angle casts a large shadow on the whole arch. (00:47:40)
Continuity mistake: Ky is leaning against the church wall motioning Magnum and Lady Hue to move. In the two shots, his shadow shifted noticeably. (01:10:15)
Revealing mistake: To make his escape from the church, Magnum turns the Mercedes around. You can distinctly see at the driver's seat the driver, which is not Tom Selleck but someone who seems to be wearing fake moustache. (01:10:50)
Continuity mistake: Buck Greene is face to the ship, held at gunpoint. When he turns around in the next shot, his right hand is significantly above the previous position (look at the yellow tag for reference). (01:24:30)
Visible crew/equipment: When Hue and Ki show up at the church looking for Michelle, three of Ki's men walk out of the church in an exterior shot, and the lowered boom microphone pops up into view at the bottom, right corner of the screen. (01:30:10)
Other mistake: In the streets of Little Saigon in the climax with TC and Rick involved, you can spot the same passersby they met with Magnum a couple days before, same clothes and all. (01:30:35)
Other mistake: Colonel Ky fires his gun at Magnum a first time when he is picking up the handkerchief. In the background, a woman in brown is walking peacefully. Cut to scared crowd all over the place. Magnum turns the corner and from the new cover shoots a couple times at Ky. Next shot Ky returns fire, but it's just another take of the first shot; the woman in brown is again walking where she was, and reacts to the gunfight only at that point. (01:30:40)
Revealing mistake: When Magnum shoots the agent in front of Bully's Tattoo Shop, he gets propelled in the air at impossible distance in a very fake trajectory with obvious wirework. (01:31:50)
Continuity mistake: In the close-up of Magnum's hand on the ground, he is looking at Ky and Michelle's feet, but there's no other person lying on the ground, contrary to the rest of the scene. (01:32:20)
Continuity mistake: There's a cut when General Hue flips Magnum on his back; the crowd witnessing the event changes from one shot to the next. (01:33:00)
Continuity mistake: The blood on Magnum's shirt when he lies in the middle of the street changes from the beginning to the end. For instance, the corner of his collar has a more sparse bloodstain in the close-up rather than at the beginning. (01:33:30)
Continuity mistake: During the episode, Magnum is missing the scar on his chest and the one on the top of his shoulder. At least the latter, carried consistently from the pilot episode, is well visible in the following.
