Continuity mistake: When Higgins raises his glass for a doomed to fail toast to the Queen, the level of so called scotch in his plastic cup changes between shots. (00:25:35)
Continuity mistake: Right after the scene at the rooftop bar is a wrap, there's a shot of TC's helicopter that features a different serial number from the normal one, and padded skids. Next shot and the skids slimmed down. They go back to the padding for other shots after Magnum photographs the cetacea. (00:27:00)
Visible crew/equipment: When Higgins places Anne Boleyn's crown in the box, just as he walks over to the hidden wallsafe, not only is a black T-mark is visible on the floor, the elegant bar table is raised on two small tacky wooden crates, in order to be taller in the following shot while Higgins pours drinks. (00:30:15)
Continuity mistake: The rosary in Father Paddy's hand changes position - look at the metal tag - before and after Higgins' exits his room. (00:32:00)
Continuity mistake: Magnum and TC are looking closely at Magnum's client punching the lights out of his sparring partner. After a brief cut to the boxer finishing the guy off, TC suddenly has a baseball hat on. (00:33:40)
Visible crew/equipment: Magnum urges Father Paddy and Faulkes to figure out who could have benefited by stealing the relic. In the following shot of the tour guide talking to the tourists, as she says, "as the ashes are no longer there, the church was a little out if our way," her chalk T-mark is visible on the ground, at her feet. (00:41:00)
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)
Continuity mistake: During the farewell to Brigadier Faulkes and Father McGuinness, the people in the background never transition from one shot to the reverse, effectively disappearing. (00:42:00)
Visible crew/equipment: At the airport, when Magnum presses Higgins to tell him all about Soo Ling, it cuts to a wide shot as the two start walking, and three tape marks (one black, two white) are visible on the floor behind them. (00:43:50)
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)
