Continuity mistake: During the after-mission chat, Alan is wearing a bandage above his left eye due to an injury he picked up on duty. If you look carefully this bandage sometimes changes between shots; it is particularly noticeable when he's in the bathroom with Tin-Tin. Also, the bandage is too small and too high up to have covered the injury adequately.
Continuity mistake: When Kalp makes his surprise appearance via Lopez's secret waterway, after shooting Scott's gun out of his hand, he holds up a test tube of Theramine. As he says, "Remarkable discovery." in the close-up, the position of Kalp's hand differs.
Continuity mistake: When Jeff and Virgil are talking about how to deal with the alligator situation at the house, Jeff says that Pod 6 would be the best choice. Yet when Thunderbird 2 arrives at the scene, it is not Pod 6 that has been chosen - it is Pod 4.
