The song in the trailer is the 'Hammond Song' by The Roches.

The film was released the same year as the vampire flick Twilight (2008) which Robert Pattison (Art) starred as Edward Cullen.

In the scene which Art talks to the boy in his old bedroom (29:30), a poster of a Cyberman from the BBC TV series Doctor Who (2005) can be seen on the bedroom wall.
