In 2009, the script was listed in The Black List. The Black List is an annual publication that names the best unproduced screenplays of the year it is published.

Director Sarah Polley chose to use the song Video Killed the Radio Star in key scenes because it was her brother's favorite song.

Sarah Polley wrote the role of Lou for Seth Rogen.

Margot: A dog is like a starter for a kid.

Lou: At least I have my testicles.

Margot: Sometimes I'm... walking along the street and a shaft of sunlight falls in a certain way across the pavement and I just wanna cry. And then a second later, it's over. I decide because I'm an adult, to not succumb to the momentary melancholy; And I thought that sometimes with Tony, she just had a moment like that. A moment of not known how or why, and she just let herself go into and there was nothing anyone could do to make it any better. It was just her and the fact of being alive, colliding.
