The new Doctor Who, David Tennant, has topped a list of Britain's best TV talent. The actor, who takes over from Christopher Eccleston, beat the likes of Jamie Oliver and Ant and Dec. Tennant heads Broadcast magazine's Hot 100, chosen by a panel of industry experts, according to a variety of press reports today. Before he was unveiled as the new Doctor Who, the 34-year-old made his breakthrough in BBC drama Casanova. "Landing the role of one of TV's most iconic characters has propelled Tennant into the big time," Broadcast said. "As yet we've had only the briefest glimpse of him as the Doctor, but if you missed his exuberant, charismatic, detailed performance as the eponymous hero in Casanova - where were you?"
