Manic Pixie Dream Girl is a term coined by AV Club writer Nathan Rabin after watching Kirsten Dunst's performance in the 2005 Cameron Crowe film 'Elizabethtown.' Rabin describes the Manic Pixie Dream Girl as a, "cinematic creature that exists solely in the fevered imaginations of sensitive writer-directors to teach broodingly soulful young men to embrace life and its infinite mysteries and adventures." The term has now grown to encompass performances as iconic as Holly Golightly in 'Breakfast at Tiffany's' to more recent performances like Zooey Deschanel's turn as Summer Finn in '(500) Days of Summer.' I spoke to Dunst just this afternoon about her award-winning role in 'Melancholia,' and when I asked her to comment on the phenomenon of MPDGs, I assumed she knew the term. Alas, she did not. The end result was myself awkwardly trying to explain to Kirsten Dunst the definition of a Manic Pixie Dream Girl -- something I did extremely poorly.
