'My Week With Marilyn': Michelle Williams' transformation completes with first trailer

It seems like its been a year since we caught our first glimpse of Michelle Williams as Marilyn Monroe in the upcoming "My Week With Marilyn." Well, just shy of the film's Oct. 9 premiere at the New York Film Festival, there's finally a trailer.

And, not surprisingly, it's pretty fantastic.

"Marilyn" isn't so much a biopic as it is a little window into Monroe's life during the summer of 1956. She was on her first trip to the U.K., filming "The Prince and the Showgirl" with Sir Laurence Olivier ( Kenneth Branagh) when she took up with a 23-year-old assistant named Colin Clark ( Eddie Redmayne).

The film is an account of the week the actress went off the radar for a week in the countryside with Clark.

"My Week With Marilyn" goes into limited release Nov. 4.
