In the interview Twiggy said the idea for the film came about after Frost featured on her Tea With Twiggy podcast to talk about her Mary Quant documentary, Quant.
Directed by Sadie Frost, the new film follows the star’s upbringing, career and relationships, and features contributions from former Beatles star Sir Paul McCartney, US actor Dustin Hoffman and actress Joanna Lumley.
Twiggy said: “In the middle of us chatting on the podcast, I asked if she was going to do any others because it was so good, and she said, ‘I’d love to do you’, because she’s fascinated with the 1960s.
During her modelling career Twiggy was known for her androgynous style, appearing on the cover of the likes of Vogue and Tatler, and she also had a career on stage and screen, with her role in The Boy Friend (1971) earning her two Golden Globe awards.
Sixties fashion model Twiggy has said she was “shocked” after mistaking a letter notifying her of her damehood for a tax notice.
