Watch Julie Delpy Online

At age fourteen Delpy obtained a role in the film Detective, directed by Jean-Luc Godard. Two years later, Delpy was cast in the title role in the film Beatrice, and used the money she earned to pay for her first trip to New York City. Delpy continued making regular trips to New York over the next few years, before finally moving there in 1990. Delpy became an international celebrity after starring in the 1990 film Europa Europa. In the film, she plays a pro-Nazi girl, Leni, who falls in love with the hero, Solomon Perel, not knowing that he is Jewish. She had to speak fluent German for the part.

Delpy was subsequently given offers to appear in several Hollywood and European films. In 1993, she was cast by director Krzysztof Kieślowski to play the female lead in Three Colors: White, the second film of Kieślowski's Three Colors Trilogy; Delpy also appeared in the other films in the series, albeit in smaller roles. She has starred in many American and European productions since then, including Disney's The Three Musketeers (1993) and Killing Zoe (1994). Delpy may be best known internationally for her co-starring role with Ethan Hawke in director Richard Linklater's 1995 film, Before Sunrise. The film received glowing reviews and was considered one of the most significant films of the independent film movement of the 1990s. Its success led to the casting of Delpy in the 1997 American film, An American Werewolf in Paris, generally considered a disappointment by critics.

In late 2001, she filmed alongside comedian Martin Short for the 30-minute film of CinéMagique, a theatre-show attraction presented several times daily at Walt Disney Studios Park in Disneyland Resort Paris. Delpy attended the March 2002 opening of the park and the inauguration of the film-based attraction, which sees her star as Marguerite - a female actress with whom Short's character, George, falls in love as he stumbles through countless classic movies. CinéMagique won the coveted 2002 Themed Entertainment Association award for "outstanding" themed attraction. Delpy reprised her Before Sunrise character, Céline, with a brief animated appearance in 2001's Waking Life, and again in a 2004 sequel, Before Sunset. The latter film was well-received and earned Delpy, who co-wrote the script, her first Academy Award nomination for Writing Adapted Screenplay. In addition, she has been nominated for César Awards three times.

Delpy has also had an interest in a career as a film director since her childhood, and enrolled in a summer directing course at New York University. She wrote and directed the short film Blah Blah Blah (1995), which screened at the Sundance Film Festival. She made her feature length directorial debut in 2002, with a film entitled Looking for Jimmy, which she also wrote and produced. 2007 saw the release of 2 Days in Paris in which Delpy not only starred in the film (with Adam Goldberg), but also directed, wrote, edited, co-produced it and wrote the original music. The film also features Delpy's real-life parents, Marie Pillet and Albert Delpy.

Delpy is also a musical artist. She released a self-titled CD in 2003. Three tracks from the album, "A Waltz For A Night", "An Ocean Apart" and "Je t'aime tant" were featured in Before Sunset.

Delpy lives in Los Angeles, California, USA and has been a naturalized United States citizen since 2001, although she also retains her French citizenship. She loves sewing and making her own clothes.
