It's icons 'r' us this afternoon, thanks to this uncannily doppelganger-like shot of Michelle Williams as Marilyn Monroe in My Week With Marilyn. The actress is togging up to play the iconic blonde in the Weinstein Company/Trademark Films co-production, now underway at Pinewood.

My Week With Marilyn is an adaptation of Colin Clark's novel, which recounts the story of Monroe's visit to Britain to film The Prince And The Showgirl with Lawrence Olivier (Kenneth Branagh) in 1956.

As you might expect, the pair don't exactly become bosom buddies. Under pressure and looking for a temporary escape from the Hollywood spotlight, Monroe takes off on a week-long jaunt with Clark (Eddie Remayne), a lowly on-set assistant, in a kind of Roman Road holiday. Monroe, recently married to Arthur Miller (Dougray Scott), gets to sample the delights of London life. Here's hoping she gives jellied eels a wide berth.

Williams joins a strong British cast that includes Judi Dench (Dame Sybil Thorndike), Julia Ormond (Vivien Leigh), Zoe Wanamaker, Emma Watson, Toby Jones, Derek Jacobi, Simon Russell Beale and Dominic Cooper. Simon Curtis (Cranford) is the man behind the camera.
