Trivia: Director Martin Campbell makes a cameo as the gasoline truck driver killed by the attempted plane bomber. (00:48:20)
Trivia: The internal shots of the hotel in Venice Bond is staying in is actually the National Museum in Prague - obviously almost every movie uses random locations, but partly it's very identifiable if you've been there, and also I've recently been there myself, and this is my site, so I'm listing it.
Trivia: The chief of police who is arrested as Bond sits at a Cafe is in fact Michael G Wilson (one of the film's producers).
Trivia: Ford was obviously the car company displayed in the movie. Right after you first see his Ford, he drives into the club and takes a Range Rover, a company owned by Ford. While Bond valets the car (poorly), every car in the parking lot is owned by Ford: Ford, Lincoln, Jaguar, Volvo. There's one exception with one parked Caddy he passes.
Trivia: Richard Branson made a very quick cameo as a passenger getting checked at a security gate, when Bond was running through Miami Dade airport.
Trivia: "Casino Royale" is actually the second Bond film that director Martin Campbell has helmed. He previously directed 1995's "GoldenEye", meaning that he is responsible for introducing the two most recent on-screen Bonds to the world. "GoldenEye" was the debut of Pierce Brosnan in the role and "Casino Royale" was the debut of Daniel Craig.
Trivia: Although it lasts for only seven minutes on screen, the opening Parkour chase took six weeks to film.
Trivia: Solange's name is never mentioned once during the film. It is only mentioned in the closing credits.
Trivia: The sinking building scene in Venice took three weeks to shoot.
Trivia: When Bond is sending his resignation there is a quick shot of his emails. If you look at the email addresses, they are all (or most of them) people who worked on the production of Casino Royale - A few I have noticed and looked up are Chris McBride (computer & video supervisor), David Hicks (lead motion graphics designer) and Neil Pinkawa (lead screen graphics artist).
