The new trailer for “The Princess” has been released.

The HBO documentary, which was among movies opening the virtual Sundance Film Festival last week, follows Princess Diana’s extraordinary life.

A synopsis reads, “Diana’s story is told exclusively through contemporaneous archive, creating a bold and immersive narrative of her life and death.

“It also illuminates how the public’s attitude to the monarchy was, and still is.”

One person calls Diana the “best thing to happen to the monarchy in centuries” in the teaser, while another voice-over says: “When you put a modern person in an ancient institution they will be destroyed.”

The clip focuses on the impact of the British press on Diana’s life, as well as the pressure she faced knowing every person had an opinion about her.

The documentary is the latest Diana film to be released, with Kristen Stewart playing the late royal in 2021’s “Spencer” and “The Crown” covering her life during the show’s fourth season.
