George Clooney said he did not have time to hit the nightclubs

Hollywood star Clooney, 42, waved and chatted to fans outside a hotel in Glasgow's west end.

He told the crowds he did not have time to sample the city's nightlife because he would be filming in West Lothian on Tuesday.

Clooney is co-producing but not starring in the �20m film which stars Adrian Brody and Keira Knightley.

Brody plays a Gulf War veteran who tries to avoid death by using his clairvoyant powers while being held in prison.

Earlier this month casting agents for the film auditioned hundreds of people hoping to be extras.

This is a most exciting event which has created a great deal of interest locally Willie Dunn West Lothian Council

West Lothian Council said it hoped the film would attract more location-hunting movie moguls to the region.

Councillor Willie Dunn said: "This is a most exciting event which has created a great deal of interest locally.

"I hope filming goes well and that this major new production will lead to others coming to West Lothian."

A former mental hospital near Broxburn in West Lothian is among the locations earmarked for the film.

Brody won an Oscar for his lead role in the acclaimed film The Pianist, while Knightley starred in Bend it Like Beckham and Pirates of the Caribbean.

The film will be produced by Clooney and Steven Soderbergh's Section Eight company in conjunction with Mandalay Pictures and German company VIP Meidenfonds.

Culture Minister Frank McAveety said the production team had looked at locations in London, Wales and Romania but had opted for Scotland.
