In 2010, the melodrama “Blue Valentine” was released. In it, Ryan Gosling and Michelle Williams portrayed how the romantic relationship of a young married couple entered a crisis phase.
An interesting fact: to naturally portray a married couple, the acting duo lived under the same roof off set.
“We shot the first part when they were young and in love, and everything was going very well. Then we took a two-week break and lived together,” the 44-year-old actress shared on the Armchair Expert podcast.

Williams admitted that it was very challenging: first to fall in love with a person for the role, and then to learn to despise them.
“It was awful. I don't want to give reasons to hate me or think I'm unpleasant,” the actress shared. However, in the end, the bold experiment earned her an Oscar nomination for Best Actress.
