Visible crew/equipment: When Alexandra is being harassed by the hagglers, she gets into a man's truck after he tells her he knows where to take her. As the truck drives out of the shot the camera is reflected in the window.
Continuity mistake: When Alexandra Rover is about to leave the apartment to go and help Nim, she is standing in front of the door debating if she can go or not (she is agoraphobic, afraid to leave her home). Notice that the baby chain is hooked to the door. Alex Rover (the imaginary adventure hero) is leaning against the wall telling Alexandra she can and must go help Nim and that she must turn the door knob. In the next scene, Alexandra turns the knob and opens the door. She never unhooked the baby chain, and Alex Rover is an imaginary character so he could not have unhooked it.
Factual error: Alex Rover travels from San Francisco in a large plane to Borneo, then a small plane to Rarotonga, then a small boat to Tuvalu, then a helicopter to the Buccaneer cruise ship (located close enough to Nim's Island at 20S-162W for her to row there). My globe shows these places to generally be too far from one another given the particular mode of transport. Borneo and Tuvalu are too far out of the way to fit with this story.
Continuity mistake: When Alex reads Nim's first e-mail reply, there's an extra sentence ("He'll be back on Thursday") that Nim never wrote.
Other mistake: After the first storm on the island, the power goes out. Nim reconnects the solar panels, and her computer boots instantly to the exact screen she was on when the power went out, which is impossible.
Continuity mistake: After Fred the lizard 'peeked' below the microscope Jack was using, he suddenly appeared a foot away from the microscope when the camera changed angles.
Continuity mistake: About halfway through, Gerard Butler is on a boat watching a whale go by. He is holding a large sextant and as he watches the whale, he moves the sextant so that it is vertical and behind his knee. The shot changes and the sextant has instantly changed to being held horizontally on his knee.
Chosen answer: No. Gerard Butler plays Alex Rover because Nim imagines him looking like her father. Alexandra Rover sees him like that merely for the sake of consistency within the film.
