Continuity mistake: Karen and Magnum have their chat in 'Nam about Thomas' gambling debt. During the scene, in one recurring angle Karen has hair down her temple, in front of her ear, which is gone in other views. (00:03:00)
Continuity mistake: When Thomas hands the newspaper to Rick, the paper is perfectly straight in close-up, then folded with the middle pointed down, then folded with the middle being raised. (00:07:00)
Continuity mistake: Magnum is talking with the administrator of the hospital, Phillip Harriman. He asks him about Dr. Jorgenson. When Harriman answers, a rather conspicuous fella with a big head of curly hair walks into the building. When Magnum walks off at the end of the scene, he comes across that same guy, who again is entering the building. (00:11:35)
Continuity mistake: After his first encounter with the annoying reporter, Magnum is swimming. He is wearing blue swim trunks. The he emerges from water to get his towel and chat with Higgins...but his swim trunks are now light brown. (00:14:10)
Continuity mistake: After denying any rumor about any more Iron Man competitions, Magnum asks Higgins about Dr. Jorgenson. His left hand is wrapped in the bath towel whenever Tom Selleck is filmed from the front, but it's bare in the views from the back. (00:15:05)
Continuity mistake: To get to the pool area, Magnum slides a door open to the left (of the screen). When he finds the body floating in the water, the underwater camera shows the background, and the door opens towards the right. (00:39:20)
Continuity mistake: Poolside, Magnum asks Daniels "Why change now?" His notepad suddenly switches side going from the left hand to the right. (00:39:55)
