Chicago Sun-Times - 11/18/2011 3.5 stars out of 4 -- "What matters is the performance by Michelle Williams. She evokes so many Marilyns, public and private, real and make-believe."
Los Angeles Times - 11/23/2011
"It's lush and vibrant when Williams is onscreen....It's hard to imagine a more unforgettable Monroe than the one Williams has given us ? except for the original, of course."
USA Today - 11/23/2011
"Disappearing into the role of the troubled actress, Williams captures the star's breathy voice and distinctive mannerisms while delving a few notches deeper."
Movieline - 11/23/2011
"Michelle Williams, as Marilyn, both anchors the movie and upends it. Miss it and you'll miss one of the finest performances of this year."
A.V. Club - 11/22/2011
"It's all compellingly staged, with Williams providing the dark, unknowable mystery at the heart of the piece."
Entertainment Weekly - 12/02/2011
"Williams knows exactly how to throw the switch that turns on MM's movie-star incandescence, then flick it off to reveal the vulnerable young woman in the dark."
Rolling Stone - 12/08/2011 3 stars out of 4 -- "What Williams does, with fierce artistry and feeling, is illuminate Monroe's insights and insecurities about herself at the height of her fame....It's a great, soulful performance."
Total Film - 01/01/2012 4 stars out of 5 -- "[I]t's Williams around which the pic revolves. And she's nothing short of heartbreaking, showing us MM at breaking point..."
Sight and Sound - 01/01/2012
"[Williams's] performance goes way beyond mere mimicry of voice and gesture -- though she gets those right too, and even does all her own singing -- into psychological re-creation."
Based on the famously missing chapter in Colin Clark's memoir THE PRINCE, THE SHOWGIRL AND ME, MY WEEK WITH MARILYN reveals the enchanted week that the then-lowly production assistant spent with the most famous celebrity of the era during the production of the classic 1957 comedy romance THE PRINCE AND THE SHOWGIRL. The year was 1956. Colin Clark was an ambitious 23-year-old determined to make a name for himself in film. As summer gets underway, Clark manages to land a position as a production assistant on the film THE PRINCE AND THE SHOWGIRL, starring Marilyn Monroe (Michelle Williams) and Sir Laurence Olivier (Kenneth Branagh). Monroe had just gotten married to playwright Arthur Miller (Dougray Scott), and the newlyweds were on their honeymoon as production got underway. Later, when Miller leaves, young Clark seizes the opportunity to befriend the platinum blonde beauty, and give her a taste of everyday life in England -- far away from the bright lights of Hollywood and the suffocating pressures of fame.
