Kristen Stewart's Princess Diana biopic "Spencer" received a rapturous five-minute standing ovation following its premiere at the Venice Film Festival on Thursday afternoon.

Both Stewart and the film's director Chilean filmmaker Pablo Larraín were present during the premiere and were seen embracing at the end of the screening as the audience inside the Sala Grande rose to their feet.

You can watch a video of the moment, captured by Insider, below:

"Spencer," which is competing for the prestigious Golden Lion at Venice, follows Stewart as a troubled and dispirited Princess Diana during a 1991 Christmas visit to Sandringham House - one of Queen Elizabeth II's private residences in Norfolk, England.

Over the course of the film and the winter break, Diana (whose maiden name is Spencer) confronts her fears and her family. She makes the decision to end her marriage to Prince Charles, played in the movie by "Poldark" actor Jack Farthing.

In a review of the film, Insider said Stewart's performance is "not only convincing but engrossing."

Earlier in the day during a press conference, Stewart told journalists that she has never felt "taller" in a film role than she did as Princess Diana during the production of "Spencer."

"I took more pleasure in my physicality making this movie than I have on anything," Stewart said. "I felt more free and alive and able to move, and taller, even."

"There are some people endowed with an undeniable, penetrating energy," she said of Princess Diana. "The really sad thing about her is that - as normal and casual and disarming in her air [as she is] - she also felt so isolated and lonely. She made everyone else feel accompanied and bolstered by this light and all she wanted was to have it back."
