Actress Helena Bonham Carter hired a psychic to communicate with the late Princess Margaret as part of the preparation for her role as the princess in the Netflix series The Crown, a television insider told The Sun.

The Crown is a Netflix original drama series that chronicles the life of Queen Elizabeth II from the 1940s to present day.

"She always likes to research her roles with as much depth as possible—and is always prepared to go that extra mile," the insider said. "So if that means using someone with supernatural powers to speak to a character who is now on the other side then Helena has no problems with doing that."

"She is naturally spiritual and open-minded and is delighted she’s had such positive feedback from the late royal," added the anonymous source.

Carter has reportedly sought psychic aid in the past—once to help with a personal haunting in her home, and another time for a situation similar to this one, in which she wished to gain insight into the life of Elizabeth Taylor for her role in Burton and Taylor.

“I was in a real dilemma about the role," Carter said. "I asked a psychic—I’m completely wacko—who was actually de-ghosting our house.”

Season 3 of The Crown is expected to be released in 2019.
