Britain's Queen Elizabeth advised Dame Kristin Scott Thomas that portraying her on stage will be a ''challenge''.

The 'Four Weddings and a Funeral' actress takes on the role of the monarch in stage production 'The Audience' - which dramatises the weekly meetings between the queen and her Prime Ministers throughout her reign - in London next month and she was given some good advice from the 88-year-old royal herself.

Discussing meeting the queen to receive her damehood last week, Kristin said: ''She asked me what I was doing next so I had to tell her. She said it would be quite a challenge.''

Kristin thinks performing on stage as the queen will be an ''extraordinary'' experience.

She told Britain's HELLO! magazine: ''Playing someone who's alive is extraordinary. Of course, this is a play, not a documentary or anything like that but we're trying to recount history.

''Whether these thing are actually said is another matter, but it's a very clever way of telling the story of the past 60 years.''

The 54-year-old star admits she is amused at the thought of being a Dame and doesn't think she fits the stereotypical image the title conveys.

She said: ''I have a hard time believing that it's really me.

''For me, the image of a dame is someone in a tweed skirt who walks around with four dogs yelling at everyone.

''I find myself laughing when I see envelopes arriving at my house addressed to me with the title Dame on them.''
