Michelle Williams' long-awaited Marilyn Monroe tribute "My Week with Marilyn" will premiere at the New York Film Festival in October, festival organizers announced on Thursday.

The film is based on the week that British writer Colin Clark worked as the sex symbols' assistant while she was filming "The Prince and the Showgirl" in the United Kingdom in the summer of 1956.

Monroe was on her honeymoon with playwright Arthur Miller during filming and Clark was told to acclimate the actress to British life when her new husband left. The film is based on Clark's diary, parts of which were published in two books. Monroe starred in the film opposite Sir Laurence Olivier, who will be played by Kenneth Branagh in "My Week with Marilyn." The film also stars Dame Judi Dench, "Harry Potter" star Emma Watson, Dominic Cooper and Dougray Scott as Arthur Miller.

"After seeing Marilyn Monroe so often portrayed in films as a caricature, it is a pleasure to see this complex personality and unique on-screen presence portrayed so well by such a talented actress as Michelle Williams," Richard Pena, program director for The Film Society of Lincoln Center, which backs the festival told Reuters.

The late actress' estate is currently battling a Spanish events promoter Mikel Barsa who plans to sell a sex tape he claims stars a young Marilyn Monroe, who was known as Norma Jeane Baker at the time. The Associated Press reports that Barsa is trying to sell the film for $500,000.

Experts say that the films authenticity is highly unlikely and Monroe's estate will be open to legal action against Barsa, as even alleging that the woman in the video is Monroe violates her intellectual property rights.

"My Week with Marilyn" will premiere at the New York Film Festival on October 9 and be released in theaters on November 4.

Monroe died in 1962 at age 36 and remains one of Hollywood's most iconic sex symbols. She is best known for her work in films like "The Seven Year Itch," "Gentlemen Prefer Blondes" and "How to Marry a Millionaire."

Williams has been nominated for two Academy Awards, for her work in "Brokeback Mountain" and "Blue Valentine."
