The title of the film is a play on a song (The Exploding Boy) which was on the b-side of the single "In Between Days" by The Cure. "In Between Days" had been used by the director and his wife as a title to a previous movie and so they decided to adapt "The Exploding Boy" to The Exploding Girl for the purpose of this film (as explained by the director himself on 14th Nov 2009 at the 50th International Film Festival of Thessaloníki, Greece).
