Richard Branson is no stranger to the cameo; as well as the mighty likes of Baywatch and Only Fools And Horses, Branson has also appeared in Around The World In 80 Days and Bryan Singer's Superman Returns. He also shows up briefly in Casino Royale, as a man getting frisked at an airport. Branson can be seen during Bond's chase through Miami Airport - he's the guy who sets off the metal detector, and is then inspected by airport security. Apparently, Branson's cameo was secured after he helped out the production, saving the film money by providing a plane at the last minute when production stalled in Prague.
