Billy-Ray Burton

, 3 1/2, son of Tim Burton and Helena Bonham Carter, won’t be among the millions of kids seeing Helena as Bellatrix Lestrange in Harry Potter and the Order of the Phoenix this summer after a slightly nerve-wracking experience with the third film. As part of research for her role, Helena let Billy-Ray, whose godfather is Johnny Depp, join her for a viewing of Harry Potter and the Prisoner of Azkaban and he barely got through the opening minutes.

The actress is enjoying motherhood and says it has made her more relaxed, which she attributes to living in her native London.

Tim has also made a habit out of filming in London and hiring British actors and crew members – something for which Helena hopes he’ll get on the British honours list so she and Billy-Ray can reap some title perks.
