Continuity mistake: Rick and TC their back to Magnum and scoff at him. Magnum chases his primadonna friends to convince them to help him. During this scene, the same rider approaches the gate, accompanied by a stable worker with a baseball cap that is first red, then yellow. (00:29:10)
Continuity mistake: Inside Higgins' study you can get a great look at Magnum's dirty shoes when he sits with his feet up on the desk. Those shoes have a blue logo on the tongue. Later there's a close-up of Magnum and Adelaide's feet when Magnum drops the gun in the stable, and the shoes are very similar but different, lacking the blue logo. (00:39:15 - 00:44:15)
Character mistake: The day of the race, Higgins reacts to Adelaide mentioning Norman as if it were the first time he ever heard the name, but he was present when she mentioned him, and the case. Not being all that involved, technically he didn't have to remember that, but he remembered the detail of the uncle, and forgetting that the woman was talking about someone being murdered, is quite odd - and is just done for the cheap gag that follows.
