British actress Carey Mulligan is set to play Eliza Doolittle in a remake of My Fair Lady, according to the film's writer Emma Thompson.
Speaking to BBC 5 live at the premiere of her latest movie Nanny McPhee, the star said they have yet to cast the male lead of Henry Higgins.
It has been reported that Hugh Grant is linked to the role.
Thompson said that she would "love him to do it", but added nothing had been confirmed yet.
When asked whether it was true that Mulligan had been cast in the musical movie, Thompson said: "I think Carey is set to play it, yes.
"But we still don't know about [Henry] Higgins. I love Hugh so I'd love him to do it, he might want to, he might not want to, so we don't know yet. But hopefully we'll make it later this year."
The musical was originally staged on Broadway in 1956, starring Julie Andrews and Rex Harrison, which became a smash hit.
It won nine Tony awards before transferring to London's West End.
In 1964 Harrison starred in a film version opposite Audrey Hepburn, which scooped eight Oscars, including best director for George Cukor.
