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.
Nim's Island (2008)
1 other mistake - chronological order
Directed by: Jennifer Flackett, Mark Levin
Starring: Gerard Butler, Jodie Foster, Abigail Breslin, Michael Carman
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.
Jack: Be the hero of your own life story.
Alex Rover: Don't hand me that line - I wrote that line.
More questions & answers from Nim's Island
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.
