Emily Blunt is best known for playing an under-nourished fashion magazine assistant in Vogue satire The Devil Wears Prada, chastising Anne Hathaway's character in one scene: "You eat carbs, for heaven's sake."
But it appears Hollywood executives are worried life is imitating art for the 32-year-old Roehampton-born actress.
In an email discussing her possible role as super-villain Scorpion in a Spider-Man spin-off, Sony Pictures chairwoman Amy Pascal wrote she was "worried" about Blunt.
"I think I saw a picture of her and she looked anorexic," Pascal told director Drew Goddard and fellow Sony executives in the missive, one in a series of emails that have just been published by WikiLeaks. Pascal resigned two months ago over the scandal.
Goddard was keen for Blunt to star in his film Sinister Six, however, earlier enthusing to Pascal: "F***. Even as I type this... Picture Emily Blunt with a Scorpion tail on... Oh goddamn it, now I might need her for Sinister Six. Or, at least, Sinister Six Two."
