Helena Bonham Carter reveals similarity with her character in 'The Crown'

Actor Helena Bonham Carter says she and Princess Margaret do not know how to keep a pretence.

The 52-year-old actor, who will play the role of the controversial royal in the upcoming season of Netflix series The Crown, says like the princess she also has "no filter".

"We both don't pretend. She was someone who didn't feign, she was utterly honest and if she felt something she would say it.

"I can often have no filter which often gets me into trouble. But there's a lot which isn't similar which is hard!" Bonham Carter told HELLO! magazine.

She added she is almost the same height as Princess Margaret and joked, "We're short when we're not wearing heels!" Vanessa Kirby essayed the iconic part for the first two installments of the show.

The third season of The Crown will premier next year.
