It is, to be fair, a hard act to follow. But if her range of expressions is anything to go by, Gaby Roslin is giving it her very best shot.
The former television presenter has taken on Meg Ryan's rather daunting role in a stage version of the movie When Harry Met Sally.
Which means she must perform that scene in the diner in which Sally convinces a disbelieving Harry how simple it is for a woman to fake an orgasm. Miss Ryan was 28 when her energetic performance helped create one of cinema's most memorable comedy scenes.
The movie, which also starred Billy Crystal, made £7million when it opened in the U.S. in July 1989.
Miss Roslin, 40, appearing at the Churchill Theatre in Bromley, South-East London, this week, carried out her challenge with a series of remarkable facial contortions.
Johnny Wrather as Harry (but best known as Joe Carter in Coronation Street) was treated to a little light moaning before his co-star moved on to howling and slapping the table.
'It's a scene which most people will have seen so it's quite hard to live up to,' a theatregoer said.
Miss Roslin, who is separated from her husband, is keen to establish herself as a stage actress and has appeared in several productions, including Chicago.
Her own verdict? 'It would be very embarrassing if my dad was in the audience. But it's a key scene, so I hope I do it justice.'
