In James Gunn’s upcoming film, it seems that the Nazis were running strange experiments in this lab. Given that many members of the Nazi party fled to South America after World War II, it makes a good deal of sense that they’d have a prison/laboratory on Corto Maltese.
According to an excerpt from Empire Magazine (via Reddit) the fictitious island of Corto Maltese will be the center of much of the action in James Gunn’s The Suicide Squad.In the movie, Task Force X is sent on a “sentence-reducing suicide mission to… Corto Maltese” to destroy a Nazi laboratory and prison.
Corto Maltese is typically portrayed as being in a state of unrest and rebellion. In The Dark Knight Returns, Superman is involved in an international incident during a rebel uprising on the island. He was there to quell the tension but the Soviet Union launched a nuke at the Man of Steel, which Clark was fortunately able to divert to a safer locale.
