Twilight vampire Robert Pattinson could be a natural in the role because he may be related to a real vampire - Count Dracula!
According to genealogists, Pattinson is a distant relative to 15th Century eastern European ruler Vlad IV Tzepesch (also known as Vlad The Impaler), who inspired Bram Stoker's Dracula novel.
In an additional twist, it is thought the 24-year-old actor's ancestors are connected to the Vlad family through the Royal family.
They believe that Princes William and Harry are Pattinson's distant cousins and Vlad his distant uncle.
Genealogist Anastasia Tyler says: "Without any myth or magic, we find royalty and vampires lurking in Pattinson's life - making his story just as supernatural as the one he's playing on screen".
