Is the movie "Queimada" based on anything real?

I assume the title is clear. I looked around, but the only “Queimada” I found is a small desert Brazilian island.

According to the IMBD review – http://www.imdb.com/title/tt0064866/ – it’s set on an island which is a Portuguese colony in the Antilles (Caribbean) – and there’s no such island there – so, probably not.

Hmmm…This was intented for GQ, not GD.

Could a moderator move this thread?
