This is one of the movies based on a real-life event that is almost entirely true to the original story. It may be because, in this case, reality exceeds fiction, so there was no need to add anything to the film to engage viewers. The movie is a recount of the story of Frank Morris and brothers Clarence and John Anglin, who managed to escape from Alcatraz. No one ever knew for sure if they survived or not. Years later, however, a letter allegedly written by John Anglin appeared where he confirmed that the 3 of them managed to survive.

The scenes were also filmed in Alcatraz, but there was a small change. The cells of the protagonists were not the ones that the original inmates occupied. The ones shot in the film belong to sector C, while the original cells were located in sector B. If you visit Alcatraz, you’ll be able to see the hole that they escaped through and the paper and plaster heads they used to cover it.
