Visible crew/equipment: After Magnum and Sue are shot at while they're standing outside the cabin, Magnum soon realises the shooter is gone. Then when Magnum finds the shell casing on the ground, during the next few shots the boom mic with its fuzzy windscreen keeps popping up into view, at the bottom of the screen. (00:27:15)
Continuity mistake: While Magnum and Sue are on the island, when Sue trips the booby trap there's a closeup of their feet and Sue is wearing tan dress shoes, but when the trapper comes out of hiding at Magnum's urging, Sue is wearing white sneakers. (00:35:10)
Visible crew/equipment: When Wainwright holds the gun on Sue and Magnum and they reach the beach, the plastic white T-mark is visible on the sand directly behind Sue. (00:36:35)
