Completely nuts.

Interestingly, that took place AFTER heat debuted in 1995.
Perhaps reality followed fiction in this case.

It's actually based on two true stories.

Here's the other one:

Factual basis. Heat is based on the true story of Neil McCauley, a calculating criminal and ex-Alcatraz inmate who was tracked down by Detective Chuck Adamson in 1964. In 1961, McCauley was transferred from Alcatraz to McNeil, as mentioned in the film.
