Alan Yentob joins Today to mark the 50th anniversary of the documentary 'Cracked Actor'.
The film follows David Bowie during one of the most prolific and fecund periods of his career as he toured America for his 1973 Diamond Dogs tour.
The result, called Cracked Actor, was part of the BBC's Omnibus strand, and described by Rolling Stone magazine as the "greatest rockumentary" ever. The film chronicled the star post-Ziggy and pre-Berlin, as Bowie was redefining both himself and popular music.
On the film's 50th birthday, a book is published today, called The Fly in the Milk: David Bowie, Cracked Actor.
Today's Amol Rajan is joined by the film's director, Alan Yentob, to discuss David Bowie, making documentaries, and the controversies that arise when working with the biggest stars.
