Jean-Marc Vallee

Vallée's earliest-known works include five music videos written and directed in August 1985. The music videos were part of a project by Les Productions Perfo 30 to produce 30 music videos in 30 days for a total budget of not over $50,000 CAD. Les Productions Perfo 30 had been founded earlier that year in May 1985 by André Fortin, Martin-Éric Ouellette and Martin Saint-Pierre, and wound up producing a total of 32 music videos, all directed during the month of August, with editing spanning September and October. Vallée was one of four directors (along with Fortin, Ouellette and Claude Grégoire) to helm directorial duties. His music videos included Wild Touch's My Chick Is In My Bed, Glockenspiel's Odeline, Park Avenue's Don't Talk To Strangers, Angel's Angel's Evolution and New News' The Splice Of Life. The music videos premiered theatrically at the Spectrum in Montreal on 1 November 1985 for a limited press screening, then officially on 9 November 1985 for the general public. The music videos later aired on Canadian television through MuchMusic.

In the 1990s, Vallée produced a number of short films that aroused considerable critical interest. In 1991, Stereotypes, a fantastique comedy inspired by some American classic films, received numerous prizes at several events, including Best Promising Director for Vallée at the Rendez-vous du cinéma québécois.

Vallée made his feature-length debut in 1995 with Liste noire (Black List), which became the highest-grossing film in Quebec that year and received nine Genie Award notimations, including Best Motion Picture and Best Achievement in Direction. In the wake of this success, Vallée moved to Los Angeles where he directed Los Locos (1998), a Western film written by and starring Mario Van Peebles, and Loser Love (1999). After these two low-budget productions, he directed two episodes of the television series The Secret Adventures of Jules Verne (2000).

During the mid-1990s, Vallée was preparing C.R.A.Z.Y. from a screenplay inspired by his own youth and that of his co-writer, François Boulay. Vallée wanted to shoot the film in the United States, but his friend Michel Côté, who also starred in Black List, convinced him to shoot in Quebec. After ten years in production, C.R.A.Z.Y. was finally released in 2005 and became one of the most successful films in Quebec history, both financially and critically.

In 2011, Vallée wrote, directed, and edited Café de Flore, a love story which connects a man and woman living in present-day Montreal with a mother and her son in 1960s Paris. The film starred French popstar Vanessa Paradis and Québécois actors Kevin Parent, Hélène Florent, and Evelyne Brochu. It was received generally positive reviews from Canadian film critics and garnered thirteen nominations at the 32nd Genie Awards. American reviews were more mixed; Variety's Boyd van Hoeij salutes the film's casting, but deems Café de Flore unoriginal, noting that "Vallée has taken what made C.R.A.Z.Y so successful, and simply tried to replicate it on a slightly larger scale. [Occasionally] similarities between the films... are so striking it almost feels like Vallée's ripping himself off".

The film was released in 2013 to critical acclaim, earning Matthew McConaughey the Golden Globe Award for Best Actor and Jared Leto a Golden Globe Award for Best Supporting Actor. The film was nominated for six Academy Awards, including Best Picture and Best Original Screenplay, and won the awards for Best Actor for McConaughey, and Best Supporting Actor for Leto, repeating the Golden Globes. Vallée also received a nomination for the Academy Award for Best Film Editing under his alias, John Mac McMurphy.

Vallée's film Wild, starring Reese Witherspoon, premiered on August 29, 2014 at the Telluride Film Festival, and was also featured at the Toronto International Film Festival on September 8 and the San Diego Film Festival on September 24. It was released in North America on December 5, 2014.

Vallée's next film, Demolition (2015), starred Jake Gyllenhaal and Naomi Watts, and opened the Toronto International Film Festival in September 2015.

In May 2015, Vallée received the National Arts Centre Award, a companion award of the Governor General's Performing Arts Awards, given to an artist in recognition of work of an extraordinary nature over the previous performance year. The film was nominated for two Academy Awards, Best Actress for Reese Witherspoon, and Best Supporting Actress for Laura Dern.

In 2017, he directed and executive-produced the acclaimed HBO miniseries Big Little Lies, winning a Primetime Emmy Award for Outstanding Directing for a Limited Series, Movie, or Dramatic Special.
