Despite going on to date for several years after making this film, Ryan Gosling and Rachel McAdams really did not get along at first. Director Nick Cassavetes told VH1: "Maybe I'm not supposed to tell this story, but they were really not getting along one day on set. Really not. And Ryan came to me, and there's 150 people standing in this big scene, and he says, 'Nick come here.' And he's doing a scene with Rachel and he says, 'Would you take her out of here and bring in another actress to read off camera with me?' I said, 'What?' He says, 'I can't. I can't do it with her. I'm just not getting anything from this.'"
Fortunately, the two worked out their differences while filming and ended up dating for a couple years.
