Born to a father who was an actor and director, Clémence Poésy made an early choice to pursue a career as an actor, getting her first assignment at the tender age of 14. Her rise was rapid thanks to good roles in French TV productions of the late 1990s and early 2000s. Her first appearance was in two episodes of the series "Un homme en colere" (1999), followed by one-offs in another show, "Les monos", and a TV movie, "Tania Borealis ou L'etoile d'un ete". She switched languages and countries for her first major role, as the ultimately doomed monarch Mary, Queen of Scots in the historical TV movie "Gunpowder, Treason & Plot" (2004). After that, the only direction was up, and the still-youthful Poésy won the plum part of French wizardry student Fleur Delacour in the 2005 installment of the blockbuster franchise "Harry Potter and the Goblet of Fire", repeating the role in a pair of sequels. She continued to land good roles in both TV and film after her first Harry Potter movie. In the former medium, Poésy played Natasha in an adaptation of the sprawling Tolstoy epic "War and Peace" (2007), and in the latter she was a pretty prostitute in the hit man comedy/thriller "In Bruges", starring Colin Farrell and Ralph Fiennes.
