Watch: Kristen Stewart Is Princess Diana in Haunting 'Spencer' Teaser

A peek at Kristen Stewart's highly-anticipated portrayal of Princess Diana is finally here, and you will have to see it to believe it.

As reported by Entertainment Weekly, Stewart stars in Pablo Larraín's "Spencer," which reportedly follows Diana as she coes to grips with her marriage to Prince Charles (Jack Farthing).

"Steven Knight's script picks up as the couple travels to the Queen's Sandringham Estate at Christmas, with their union having long since grown cold, and rumors of affairs and divorce plaguing their stay," reports EW from the film's synopsis. "Though they engage in typical holiday fare like eating, drinking, and hunting, Diana works through the inner turmoil of her personal life in a complete 'imagining of what might have happened during those few fateful days.'"

Attendees of Cinemacon were the first to see the footage, which features Stewart and Farthing squaring off over a pool table in the royal estate.

"The film has been heavily tipped by pundits as a potential contender at the upcoming Academy Awards, with particular focus on Stewart's performance after the actress made a stark transition from filming commercial blockbusters like 'Twilight' to well-received prestige dramas such as 'Clouds of Sils Maria' and 'Personal Shopper' in recent years," reports EW.

"Spencer" will reportedly debut at the Venice International Film Festival in September. It is set to screen at the 2021 Toronto International Film Festival shortly thereafter.
