This is Motu Rimatiai which is part of Tetiaroa, an atoll in the south Pacific that used to belong to Marlon Brando
Tetiaroa, one of the Society Islands, is an atoll located 59 km (36.5 miles) due north of Papeete, the capital of French Polynesia located on the island of Tahiti. Tetiaroa is administratively part of the commune (municipality) of Arue. Tetiaroa has one inhabitant: Marlon Brando's son Teihotu Brando. In 1789, three deserters from the Bounty became the first Europeans to visit the island during the ship's 23 week stay in Tahiti. It was after departure that the famous mutiny on the Bounty took place. In 1904, the royal Pomare family of Tahiti gave the island to dentist Johnston Walter Williams. As a private island it passed through the hands of other owners until 1965, when Marlon Brando, after filming Mutiny on the Bounty, bought it outright from William's daughter. Brando lived on the island on and off until 1990. At various times he talked of plans to develop a resort on the island, but the enormous costs involved made it financially impossible for him to carry through on his ideas.
