YOUNG WOMAN AND THE SEA
Daisy Ridley (swim)suits up to play a real-life trailblazer.
Back in 1926, Gertrude ‘Trudy’ Ederle became the first woman to swim the English Channel, arriving home to a New York ticker-tape parade. If you’ve never heard of her, don’t feel too bad – neither had Joachim Rønning, the filmmaker bringing Ederle’s extraordinary life to the screen.

I think you can really feel it.’
This consideration also extended to Ridley, who spent ‘weeks and weeks’ in the sea to film the crossing. ‘Daisy’s swimming in 15 or 16° Celsius water on a daily basis, and never complaining,’ Rønning recalls. ‘I had to drag her out when she was hypothermic!’
For Rønning, currently in production on Tron: Ares, the film marks a return to the verisimilitude of his 2012 waterbased breakthrough, Kon-Tiki. ‘I have two careers,’ Rønning notes. ‘I’m making these big tent-pole movies, which are v
