We've been following Michelle Williams's transformation into Marilyn Monroe for her role in My Week With Marilyn with some curiosity, and now, with the film set to premiere at the New York Film Festival this Sunday, the first trailer for the flick has been released.

Here's Williams, curled and primped, cooing breathlessly with an accent that sounds somehow both British and Southern, toying with a young assistant (Eddie Redmayne) on the London set of Laurence Olivier's The Prince and the Showgirl. From the two minutes we've seen, Williams does an admirable job of not turning the whole thing into a complete caricature, though her physical discrepancies are a still a bit jarring. See for yourself below, and keep an eye out for bonus starlets like Emma Watson.
