Director and producer Jean-Marc Vallée, who won an Emmy for directing the hit HBO series “Big Little Lies” and whose 2013 drama “Dallas Buyers Club” earned multiple Oscar nominations, has died. He was 58.

His representative Bumble Ward said Sunday that Vallée died suddenly in his cabin outside Quebec City, Canada, over the weekend.

A rep confirmed to People that the cause of death was a heart attack. Deadline reported, based on multiple sources, that Vallée had been preparing to receive guests, and likely died on Dec. 25 before being found the following morning.

Vallée was acclaimed for his naturalistic approach to filmmaking, directing stars including Reese Witherspoon, Nicole Kidman, Amy Adams and Jake Gyllenhaal over the past decade.

The director’s breakthrough 2005 film “C.R.A.Z.Y.” was one of the most celebrated Quebecois films of the ’00s, earning 11 Genie Awards, including Best Motion Picture.

He directed Emily Blunt in 2009′s “The Young Victoria”, and followed it up with the acclaimed 2011 French-Canadian film “Café de Flore”.

Vallée became a sought-after name in Hollywood after “Dallas Buyers Club”, featuring Matthew McConaughey and Jared Leto, earned six Academy Awards nominations, including best picture.

He often shot with natural light and hand-held cameras and gave actors freedom to improvise the script and move around within a scene’s location. The crew roamed up and down the Pacific Coast Trail to shoot Witherspoon in 2014′s “Wild.”

“They can move anywhere they want,” the Canadian filmmaker said of his actors in a 2014 interview with The Associated Press. “It’s giving the importance to storytelling, emotion, characters. I try not to interfere too much. I don’t need to cut performances. Often, the cinematographer and I were like, ‘This location sucks. It’s not very nice. But, hey, that’s life.’”

He re-teamed with Witherspoon to direct the first season of “Big Little Lies” in 2017, and directed Adams in 2018′s “Sharp Objects,” also for HBO. Vallée won DGA awards for both.

Witherspoon reacted to the tragic news on Twitter, writing, “My heart is broken.”

Her “Big Little Lies” co-star Shailene Woodley also shared her devastation on her Instagram Stories, writing, “I am in shock. Complete and utter shock,” adding, “It doesn’t make sense. Maybe  tomorrow you’ll be there laughing saying it was just a satirical short film you made. That’s it’s not real.”

Remembrances for Vallée poured from fans, colleagues and acquaintances in on social media, including Justin Trudeau.
