Timothy Goodman and Jessica Walsh of 40 Days of Dating spoke to Cosmopolitan about which actors they'd like to cast to play their roles for the film adaptation of the project.

The duo revealed that they will be consulting writers on the film adaptation, which has been picked up by Warner Bros.

Goodman suggested that they would not have complete control on the work. "What Jess and I created will always exist in its true form online. Anything else that's not necessarily authored by us, it's a little bit... it's different. I don't want to say "out of our hands"...It's not necessarily our piece of art," he said.

The duo also went on to talk about which actors they'd like to cast to play them in the film. Walsh was least interested in who would play her, suggesting that she was more concerned about the writer and director. Goodman said that Lizzy Kaplan would make sense for Walsh's character but that people had also been suggesting the likes of Aubrey Plaza and Keira Knightley. For himself, he suggested Paul Bettany, based on their physical likeness.

Walsh also revealed that she was currently in a relationship. She found her match on OKCupid about a month after the experiment ended and before the duo started posting about it online. 

Michael Sucsy (The Vow, Grey Gardens) will direct the film and Lorene Scafaria (Nick and Norah's Endless Playlist, Seeking a Friend for the End of the World) will pen the script. Michael Sugar, Joy Gorman and Bard Dorros will produce for Anonymous Content and Ashley Zalta will be a co-producer. Anonymous Content manages the director and scribe.

Walsh and Goodman started the experiment to explore what it took to make a relationship work in New York and if good friends could make for good lovers. Both Manhattanites struggled in past relationships and decided to see each other for 40 days, going on at least three dates a week and having strict rules for their relationship. The couple filled out a daily questionnaire, visited a couple's therapist once a week and promised not to date or have sex with anyone else. They documented everyday of this trial period and fans could follow their relationship on their website. The project ended with the couple parting ways.

Reports noted that even before the 40-day term was up, many producers were vying for this project. Reese Witherspoon, Josh Schwartz and Michael Costigan were assigned the project at one of several studios in the mix. After aggressively pursuing the project, Warner Bros finally landed the deal with Sarah Schechter. CAA brokered the deal.
