The fictional island of Genosha will be a key location for 20th Century Fox's X-Men: Dark Phoenix. Michael Fassbender has told Entertainment Weekly that his character, Magneto, has set-up a mutant sanctuary which writer/director Simon Kinberg dscribes as "the mutant homeland."
“He’s set up this place for mutants that don’t a home to go to and they can seek refuge there,” Fassbender aid. “They have to work as a community but it’s a safe place for them and they’ll be accepted.”
The film will start in this island, with Jean Grey/Phoenix (played by Sophie Turner) will come to the island to ask Magneto for helm.
“There’s a suspicion there on his part when she arrives," said Fassbender.
In comic books, Genosha is a fictional island off the east coast of Africa. Originally home to an Apartheid-esque civilization who feared and imprisoned mutants, but after a series of regime changes the United Nations gave it to Magneto for a mutants-led country. It prospered for a time with a population exceeding 15 million mutants, but was decimated by Cassandra Nova in Grant Morrison and Frank Quitely's New X-Men run. In the alternate reality of House of M, Genosha was the capital under the reign of Magneto.
X-Men: Dark Phoenix opens in theaters November 2.
