Michelle Williams is in negotiations to co-star with Julianne Moore in Todd Haynes’ next film, “Wonderstruck.”

Amazon Studios will finance, produce and distribute the movie. Based on Brian Selznick’s critically acclaimed novel, Ben and Rose are children from two different eras who secretly wish their lives were different. Ben longs for the father he has never known, while Rose dreams of a mysterious actress whose life she chronicles in a scrapbook. When Ben discovers a puzzling clue in his home and Rose reads an enticing headline in the newspaper, both children set out on quests to find what they are missing that unfold with mesmerizing symmetry.

Christine Vachon’s Killer Films is producing along with Pam Koffler and John Sloss. Brian Bell is exec producing.

Killer and Haynes recently teamed on “Carol,” starring Cate Blanchett and Rooney Mara. Amazon Studios executive Alan Khamoui will oversee the project on behalf of the company.

Williams, a three-time Oscar nominee, has always participated in projects with strong pedigree, with her most recent credits already generating 2016 award season buzz. Those credits include “Manchester by the Sea” and “Certain Women,” both of which were hits with the critics at this year’s Sundance Film Festival and are expected to draw similar praise from awards pundits.

She has also received rave reviews on Broadway for her role opposite Jeff Daniels in “Blackbird.”

Williams is repped by WME, Brillstein Entertainment and Bloom Hergott.
