EXCLUSIVE: Julia Ormond is playing Vivien Leigh after Catherine Zeta-Jones dropped out, and Dougray Scott is playing Arthur Miller. Filming starts today in London on the feature, which is shooting for 7 weeks at Pinewood and on location in and around the city. Michelle Williams is cast as Marilyn Monroe alongside Kenneth Branagh (Laurence Oliver), Judi Dench (Dame Sybil Thorndike), Dominic Cooper, Emma Watson and Derek Jacobi with Eddie Redmayne playing Colin Clark, the young assistant on the set of the 1956 film The Prince and the Showgirl who helped the star escape her pressure-cooker Hollywood career for a brief week. Directed by Simon Curtis (BBC TV’s Cranford) and produced by David Parfitt (Shakespeare In Love), the film is based on Clark’s diaries and has been adapted for the screen by Adrian Hodges. Parfitt’s Trademark Films is the production company, while The Weinstein Company is financing and distributing. BBC Films and Lipsync Productions are co-financing the film, which was developed in association with the UK Film Council and BBC Films.
