There's this character named Parker; mostly in books, but recently in a movie named "Parker." I liked some of the books, so I saw the movie. Then I was curious to know which book it was based on. It's Flashfire… although plenty changed in the movie. The book starts with a bank heist; the movie starts with an Ohio State Fair heist. OK, that probably made for more interesting scenery than a bank would have. The book also doesn't try to make Parker such a sympathetic character: he declares blood feud on some folks for not-following the plan. This is in character, but the movie sidestepped the whole Parker's-pretty-messed-up thing.
