David Bowie

British singer-songwriter noted throughout his life for his chameleon-like ability to change personas, his exploration of gender fluidity and his experimentation with musical genre - although who was not noted for his broad acting range. Nor - certainly in the case of cinematic sudoku - did his transformational abilities extend to convincing Eastern European accents.

When the 10 Commandments of Wittertainment was being compiled, "Thou Shalt Not Cast David Bowie" was the one that received the most suggestions from listeners. Nevertheless, it failed to make it into the final list.

That said, Performance director Nicholas Roeg was once asked, “why have you cast David Bowie, he’s not an actor” and Roeg replied, “have you seen him on stage? That’s acting.”

Mark Kermode is firmly of the belief that Johnny Depp was copying Bowie copying Anthony Newley with his performance in Sweeney Todd: The Demon Barber Of Fleet Street; equally, he felt Captain Jack Sparrow was much closer to Bowie than he was to Keith Richards.
