Christian De Metter was born in the Parisian area, and studied advertisement for a short while before embarking on an artistic career. He did a variety of commercial jobs, including model making and illustrations for music magazines, and began his first comics project in the early 1990s. The trilogy 'Emma' wasn't published until 2000 in the Trinkel collection of the publishing house Soleil. Between 2001 and 2003 he made the graphic novel diptych 'Le Curé' with Laurent Lacoste for the same collection.
He teamed up with scriptwriter Richard Marazano to create the detective thriller 'Dusk' for Les Humanoïdes Associés in 2000 and 2002, and with Thomas Bénet for the esoteric 'Swinging London' for Soleil in 2004 and 2005. De Metter won the Audience Award for 'Le Sang des Valentines' (Casterman, 2004), his book about World War I in collaboration with Catel, during the Angoulême Comics Festival in 2005.
He then began an association with Éditions Casterman for a series of solo graphic novels, including 'Vers le Démon' (2006), 'Figurec' (2007), 'L'Oeil était dans la tombe' (2008) and the comics biography 'Marilyn, de l'autre côté du miroir'. The publisher also released his adapation of Dennis Lehane's 'Shutter Island' (2009), Armitage Trail's 'Scarface' (2011) and Douglas Kennedy's 'Piège Nuptual' (2012).
