Rachel Weisz no longer stays in character between scenes.
The ‘Favourite’ star – who has son Henry, 12, with ex boyfriend Darren Aronofsky and a five-month-old daughter with husband Daniel Craig – used to try and stay "focused" even when the cameras weren’t rolling, but as she’s got older, she’s learned to appreciate the importance of letting go.
She told OK! magazine: "I think when I started out, I tried to stay in character, whatever that would mean, or stay focused on the scene after the director said ‘cut’ – and I never do that now.
"For me now, it’s really important to ‘cut’ and then it’s gone and I just think about anything else but the fiction."
While preparing for ‘The Favourite’, director Yorgos Lanthimos had Rachel and her co-stars Emma Stone, Olivia Colman, Nicholas Hoult and Joe Alwyn, doing a number of "ridiculous" things in order to feel comfortable with one another.
She revealed: "We did ridiculous things together for three weeks. It was the court of Queen Anne, so it was all the characters of the inner court – we spent three weeks playing games.
"And we were taken to the edge, the very edge, and then maybe pushed over the edge into the most ridiculous things that you could possibly do and be.
"Totally silly, like foolish, ridiculous, absurd. So that when we were on set, nothing could ever be as ridiculous again."
The 48-year-old actress is proud that the movie offered so many "very complex" portrayals of women.
She said: "The thing we’ve heard a lot from people is how surprising it is that there’s a film where there are three women who are complicated, layered, powerful and not likeable.
"And it surprised me, sadly, that there have been very few films in the last decade that have not one or two but three very complex female roles."
