'Bourne Identity' director Doug Liman adapting spy film 'The Tourist'

Doug Liman will adapt The Tourist.

The Bourne Identity helmer has signed on to produce and direct the film based on Olen Steinhauer's espionage novel, reports Deadline.

The book centres around burnt-out spy Milo Weaver, who works for a secret US agency that battles global crime.

A newfound sense of happiness is threatened when he is drawn into the investigation into the death of a hired killer he had been tracking.

The film is expected to be released under a different title following the Angelina Jolie and Johnny Depp-starring 2010 thriller The Tourist.

Liman also directed Go and Mr & Mrs Smith. He is currently shooting the Tom Cruise sci-fi movie All You Need is Kill.
