I can’t remember the name of a movie. It was about a man that was very quiet(probably autistic) and shy, and lived in the suburbs. He begins to work for a mobster as a hitman, because he is very good at shooting and doesn’t feel remorse(as he is autistic). Finally he kills his boss and leaves the business, and gets a girlfriend who he tells that he was a killer, but she doesn’t care and then the movie ends with both being together in the bed or something like that.
I think in spanish it was called “A sangre fria”(that translates “In cold blood”). However I searched for that name and found another movie that is much older(from 1967, when the movie I’m looking for is from the 90s or early 2000s). I don’t know why, but I think Dustin Hoffmann was in it(not sure anyways). So, can you help me?
