In July 2014, it was announced that Posey had signed on to co-star in Woody Allen's mystery drama "Irrational Man" with Joaquin Phoenix, Emma Stone and Jamie Blackley. The film had its world premiere on May 16, 2015, at the 2015 Cannes Film Festival. In July 2015, Parker revealed that before being cast in the film, she had considered quitting acting, as she feared that she "saw the independent film movement go away from me ... it's a world market now. They're made from real star power. Whoever's hot at the moment." When Allen cast her, she cried, as "the independent film way of working is something that was in my bones. It's like being a part of a punk band but no one's singing punk rock anymore. Only a few bands are able to play, and Woody Allen is one of them. That's why I cried. It was a relief."
