AceShowbiz - The actor son of The Queen's chief accountant Sir Alan Reid has joined the cast of the upcoming "William & Kate" TV movie - as Prince William's best pal Guy Pelly. Richard Reid originally auditioned for the role of the prince, but that part went to fellow newcomer Nico Evers-Swindell.

Reid admits he was relieved when he learned he wouldn't be playing the grandson of his father's boss - because he fears he would have had to turn the part down. He explains, "It probably wasn't a role I'd be able to do at the end of the day. I think my dad would have stepped in and put the brakes on it."

Reid admits he has never met Pelly, but he hopes William's pal likes his portrayal: "He sounds like a lot of fun. He's definitely the kind of person I would like to spend a night with drinking."
