Corrected entry: The boy travels on the plane with a blow gun, a bow and arrow, and a long wooden spear. What airport allows that?
Corrected entry: In the begining, when Tim Allen leaves the boat to find his wife, he takes nothing with him. Yet later, when the boatman leaves, Tim has his bags, computers, and technical stuff.
Correction: This is not a mistake because after the boat driver left, the children on the island were playing with his equipment. Meaning that the boat driver took his things out before leaving. So, therefore Tim Allen had his things all along.
Correction: If it were explained to the airport that they were cultural things, or heirlooms, the airport would probably allow him to take those things (albeit closely monitored). Keep in mind that this was the pre 9/11 world, where airlines were much more lenient than they are now. In this day and age, they probably wouldn't allow this.
