Whether the story is true or not, the tale of Colin Clark's week-long romp with the most famous woman in the world is one of the most fascinating to make it to theaters this year. But make no mistake, the spotlight here belongs to Michelle Williams and her brilliant portrayal of Marilyn Monroe. As soon as she steps off the plane at Heathrow Airport, Williams takes us on a wild journey of fun, frustration and, ultimately, heartbreak. The walk, the talk, the look -- it was more than an impersonation, it was Williams totally immersing herself in the character. Bonus points for Kenneth Branagh, who plays a prickly, midlife-crisis version of Sir Laurence Olivier, putting up with Monroe's shenanigans. No, Olivier may not have fallen for Marilyn in 'My Week,' but we sure as hell did. -- A.S.
