I think is a novelization of the screenplay. It's a little darker than the movie, at least the televised version. There are a few differences, but overall it's the same & one of my favorite flicks. It clearly makes the point that the warden's son is one of the subterranean cannibals. (I think Snake cuts off his fingers which have his name tattooed on the knuckles as he tries to move a man hole cover.)

As a book, it's a quick, fun read - if you like action & some horror. Others have compared it to Mad Max & I think that's a good comparison. The hero is more overblown - everyone knows Snake Plisken. He's a legend & lives up to it. Lots of fun. ( )
