Emma Thompson has opened up about shooting a nude scene for her new film 'Good Luck to You, Leo Grande'.

The dramedy sees Emma Thompson play a widowed schoolteacher who hires a male escort, played by Daryl McCormack ('The Wheel of Time', 'Pixie') for a date.

The full-frontal nude scene involves Nancy taking off a robe and look at her naked body in a mirror ahead of the date.

"It's very challenging to be nude at 62," Emma Thompson reflected on doing her first nude scene. But she also felt she couldn't have done it sooner either.

Speaking at a virtual Sundance Cinema Cafe discussion (via EW), the actress said: "I don't think I could've done it before the age that I am.

"And yet, of course, the age that I am makes it extremely challenging because we aren't used to seeing untreated bodies on the screen."

Emma Thompson spoke about how she and her co-star McCormack rehearsed in the nude for the movie, while their director Sophie Hyde also disrobed.

"Sophie, Daryl, and I rehearsed entirely nude and talked about our bodies, talked about our relationship with our bodies, drew them, discussed the things that we find difficult about, things we like about them, described one another's bodies," she shared.

She also spoke of the "dreadful demands" pressed on women to have perfect bodies.

"Nothing has changed in the dreadful demands made upon women in the real-world world but also in acting," she said.

"This thing of having to be thin is still the same as it ever was, and actually in some ways I think it's worse now."

'Good Luck to You, Leo Grande' premiered at the Sundance Film Festival last weekend. A release date for cinemas is TBC.
