Miscellaneous Due to its location and relative security—the island is off-limits to the public for the most part (cameras are prohibited on the premises so pictures of the area, except from the outside, are rare)—many urban legends exist regarding the island, the two most popular being that the island is home to a correctional facility or prison and that parts of the movie RoboCop were filmed there (due to its mention in the movie as the location).
