fame

The idea of mirror life was first floated in 1860 by Louis Pasteur, of vaccination, fermentation and pasteurization fame.

"It was patently obvious to me from the very beginning that that level of fame is too expensive a price to pay," he said.

Theakston rose to fame as a TV presenter in the 1990s on BBC shows such as The Ozone, children's Saturday show Live & Kicking, which he presented alongside Zoe Ball, and Top of the Pops.

He would eventually shift focus back to the big screen to attack Hollywood's devilish tricks of fame, glamour, deceit and identity loss, in films unofficially known as his Los Angeles trilogy.

Another Oscar-tipped film is A Complete Unknown, which follows Bob Dylan's rise to fame in the 1960s.
