VarietyBut the film belongs to Williams, whose tour-de-force turn conflates three Marilyns: the lost, damaged little girl who seeks to escape others' expectations and return to simpler childhood days; the sexy superstar who impishly poses with a wink in complicity with her public; and the actress playing a pre-scripted part. The genius of the performance lies in the way Williams stresses the interconnectedness of these personalities: The neediness fuels the impudence, the vulnerability turns sexually provocative, and the little girl and sexpot together drive the screen role.
Hollywood ReporterThe luminous Michelle Williams gives a layered performance that goes beyond impersonation in My Week With Marilyn. Playing both the damaged, insecure woman and the sensual celebrity construct, as well as the role with which Marilyn Monroe was struggling during a particularly difficult shoot, Williams gets us on intimate terms with one of Hollywood’s most enduring and tragic icons. If much of what surrounds her in Simon Curtis’ biographical drama is less nuanced, her work alone keeps the movie entertaining.
Emanuel Levy (hated the film, but thought she did the best she could)An actress with an already established impressive range (Oscar nominee for “Brokeback Mountain”), Michelle Williams gives an immensely endearing performance as Marilyn Monroe. The good thing about her work is that though she does not try to impersonate the iconic figure, she very much captures the essence of Marilyn the movie star—if not the “real life” woman; the faults are in the writing rather than in her acting.


i just wanted to say the same thing...although i think her overall body has changed a bit since then
