It Was Difficult To Find The Perfect Island
Though parts of the film were shot in Memphis and LA, the majority of the film was shot on an island off of Fiji. However, finding the perfect spot was difficult because the island couldn't look like a paradise. It had to look menacing and impossible to survive on. In order for Zemeckis to lock down the island of Monuriki he had to learn Fijan customs in order to earn the approval of the family who owned it.
