The question now is who will play Kelly. We cull some possibilities, below.
Kelly is probably best remembered as one of Alfred Hitchcock's ice princesses in Dial M for Murder, Rear Window and To Catch a Thief, as well as George Seaton's The Country Girl, for which she won an Oscar in 1955 (the same year she met Prince Rainier, whom she subsequently married). Casting Kelly, who was 32 at the time when the film is set, will be as tough as casting Elizabeth Taylor in Martin Scorsese' Furious Love (which has no news of late, which may indicate trouble).
Some names that we anticipate being thrown in the mix during casting conversations (these are not our recommendations) are:
Rachel McAdams, Blake Lively, Amanda Seyfried, Carey Mulligan, Emma Watson, January Jones, Diana Agron, Elizabeth Olsen, Brit Marling, Kate Bosworth, Rosamund Pike, Reese Witherspoon, Michelle Williams; [UPDATE] Diane Kruger, Charlize Theron.
Of those actresses, we might consider as real possibilities Pike, Marling, Olsen, McAdams, Kruger or Theron. In the capable-but-wrong-for-the-part category there's Williams and Mulligan, and in the please-Hollywood-you-should-know-better pool there's Lively, Seyfried, Watson, Jones, Agron and Bosworth.
Tell us what you think.
