Continuity mistake: Magnum walks back towards Charlie after talking to Detective Gordon Katsumoto. TC by him is in a different spot between shots, one step or two steps close to him, which means being in the sun or not depending on the shot. (00:25:10)
Continuity mistake: Magnum and TC pull over and shout at the man who just came out of the safety box deposit with a briefcase. Behind Magnum when he shouts "Russell!" you can see a woman with a baby stroller, wearing a teal top. She is getting inside a building. In Russell Chang's view, that woman is still far behind and has yet to reach the building. (00:29:10)
Continuity mistake: At the end of the episode, Rick ask to say a few words. In the wide shot ("Thank you"), Higgins is leaning her head on the left arm, elbow on the table. Closer view, and she is chilling all the way back on the chair. (00:36:55)
Continuity mistake: Toni thanks Rick at the end of the episode with the gift of a plant. When they are still by the gazebo, the flower is pointing different directions between shots. The plant also looks bent at a rather sharp angle in the shot when she says "I can't stay", but it's straight and fine in the rest of the scene. (00:37:30)
Continuity mistake: Higgins shows Magnum the phone with Katya in the eye of the camera; her pinky finger is right at the angle of the phone in the frontal view, closer to the other fingers in the reverse shot. (00:01:55)
Continuity mistake: Katya meets Magnum at the beginning of the episode. She sits on the couch in the wide shot, and the couch is strongly sunlit. The natural light in the rest of the scene is much softer and barely noticeable. (00:02:15)
Continuity mistake: The two guys who stalk Magnum take off and almost run him over. You can see them drive down a road as Magnum tumbles on the asphalt to avoid them. Then Magnum gets up, has a little exchange with Rick as they both gingerly hobble towards the car, and he finally starts it and drives off...and in the 10 seconds this takes, the car is still basically at the same spot as before. Slowest getaway ever. (00:07:20)
Continuity mistake: The car chase opens with the 2 cars driving past a Walmart, with the sign distinctly visible. A minute later, when the police joins in and Magnum says "Maybe not", the cars speed past the same Walmart as if they drove in circle. (00:07:40)
Continuity mistake: Magnum bursts into John Black's apartment;he explains to him that Katya sent him, and the man lowers his hands. They are back up in the reverse shot that follows. (00:17:05)
Continuity mistake: Magnum has been talking with Higgins (and then with the home invaders) through the phone placed in the dashboard. When Sergei carjacks him, he's lucky enough to have his phone in the back pocket of his pants. (00:22:00)
Continuity mistake: Higgins says "What if it didn't?" once she is free; she touches her forehead, the camera cuts away, and she is repeating the gesture in a separate shot. (00:33:15)
Continuity mistake: In one scene a police car (number 412) is T-boned in the right rear quadrant. A spin shot of the car shows that quadrant dented and scraped. In a later scene the same police car driven by TC makes a left turn. There are no dents or scratches on the car. (00:33:00 - 00:34:15)
The Day It All Came Together - S1-E20

They go home, Magnum gets arrested by the Secret Service, is taken for an interrogation, is taken to a house where they find some counterfeit money and two bodies. Magnum is released and stays at the house with HPD, and then he and Higgins go back to the car and they leave. According to Magnum's wristwatch, only ten minutes have elapsed. (00:09:00)
