Question: Hancock and Mary are fighting in the street and the tornados are swirling. When it shows Hancock, just before they pounce each other, there is a transformer like thing running across the street from left to right behind cars. What is that? (01:07:00)
Answer: The scene takes place on Hollywood Blvd, which is known for having people dress in costumes (and tourists take pictures with them, usually for money). There are also people who, as part of their costume, wear stilts. There was a guy who wore stilts as part of his seaweed monster costume who claims that's him, although in the film, the creature seems more robotic than seaweed covered. It seems the film makers were going to use this mystery extra for a more iconic establishing shot, but forewent it and so this is all we see of him.
Answer: I don't remember the guy's name, but he's a Hollywood Blvd street performer who wears a really well done, Transformers, Bumblebee costume.
Answer: Well my best guess after watching it and freezing the frame is that it's supposed to be someone in a costume. The street they are at has a theater, so there could be a premiere and someone is doing PR or advertisement dressed as a character. It's definitely someone on stilts wearing a cowboy hat and some kind of body armour.
Question: I've played it over and over and still can't figure out what the bully kid Michel says, right after Hancock lands in the street. Is it in French?
Answer: "He is an asshole" Is the correct answer. In English. Not French.
Answer: Yes, he basically says that he's going to tell his mother and the police.
Answer: He is trying to piece together his memories so he can understand his past.
