A prolific Gallic actress with a distinct onscreen presence, Clémence Poésy kick-started her career in a series of films produced in her native France, then gradually expanded her scope to include European and (later) U.S.-based efforts. Poésy signed for one of her first major parts with a supporting role opposite the legendary Carole Bouquet and Michel Duchaussoy in Francis Palluau's hostage-themed comedy Bienvenue Chez Les Rozes (2003). She then evoked the period flair of Mary, Queen of Scots with her portrayal of that character opposite Robert Carlyle in Gillies MacKinnon's U.K. miniseries Gunpowder, Treason and Plot, and then tackled a lead in the German comedy drama Olga's Summer (2004). In that film, Poésy played Olga, a 16-year-old who falls madly in love with a much older man and runs off with him to the French Rivera. Poésy subsequently achieved international crossover success and made her Hollywood debut as Fleur Delacour in the family-oriented big-budget fantasy Harry Potter and the Goblet of Fire (2005) and essayed a romantic lead opposite Colin Farrell in Martin McDonagh's steel-tough action-drama In Bruges (2008).
