Gillian Anderson has become the latest American star to grace the West End stage.
The X-Files actress made her debut before the critics in a role far removed from FBI agent Dana Scully.
In the play What The Night Is For, she plays a married woman re-united with her former lover in a hotel room for one night.
The two-hander, written by Michael Weller, and co-starring award-winning stage actor Roger Allam, opened at London's Comedy Theatre.
Anderson, once voted the world's sexiest woman by a men's magazine, said she had long harboured an ambition to appear in the West End.
"I have been looking for something for a while and when this play landed on my doorstep I loved it and knew I had to do it," she said.
The 34-year-old, who recently bought a £1.4 million flat in Notting Hill, is no stranger to life in Britain.
She moved to London with her parents at the age of two and stayed until she was 11.
The X-Files recently ended after nine years but Anderson will be back partnering agent Mulder, played by actor David Duchovny, in another big screen version of the sci-fi hit.
