where was the movie christmas island filmed

The movie "Christmas Island" was filmed on the island of Nauru, a tiny island nation in the Pacific Ocean. Nauru is a remote location and not a typical holiday destination, which made it an interesting setting for the movie. The cast and crew spent several months on location, filming in various locations around the island, including the main city of Yaren. Nauru's unique landscape and culture provided a unique backdrop for the movie's story of a group of strangers stranded on a deserted island during the Christmas holidays.
