Although not mentioned by name, the "vampire book" that sparks an argument between the two main characters is based on "Twilight". Elizabeth Reaser, who plays Ana in this film, also plays Esme Cullen in the "Twilight" movies. In the film, the book's title is "Lunar Moon". Its cover is similar to that of "Twilight".
There was a storyline with Michael Weston as Miles, a friend of Jesse who is trying to go to Spain but has several issues that keep him from going. All of his scenes were filmed but not in the movie; they are featured in the Bonus section as Deleted Scenes.
