After small appearances and performances in theatre, Cotillard had occasional, minor roles in television series such as Highlander—where she had her first English-speaking role aged 17. Her career as a film actress began in the mid-1990s, with minor roles in Philippe Harel's The Story of a Boy Who Wanted to Be Kissed (1994), which was her feature film debut at the age of 18, and in Arnaud Desplechin's My Sex Life. . . or How I Got into an Argument, and Coline Serreau's La Belle Verte (both 1996). Also in 1996, Cotillard had her first leading role in the television film Chloé, directed by Dennis Berry, with Cotillard starring as a teenage runaway who is forced into prostitution, opposite Anna Karina. In 1998, she appeared in Gérard Pirès' action comedy Taxi, playing Lilly Bertineau, the girlfriend of delivery boy Daniel, played by Samy Naceri. The film was a hit in France and Cotillard was nominated for a César Award for Most Promising Actress. She reprised the role in Taxi 2 (2000) and Taxi 3 (2003).
