What is Young Woman And The Sea about?

In an attempt to really get under the skin of Gertrude Ederle, this biopic explores how, “through the steadfast support of her older sister and supportive trainers, she overcame adversity and the animosity of a patriarchal society to rise through the ranks of the Olympic swimming team and complete the staggering achievement – a 21-mile trek from France to England”.

Who stars in Young Woman And The Sea?

Ridley takes the lead in this one as Gertrude ‘Trudy’ Ederle, while Tilda Cobham-Hervey appears as Gertrude’s sister, Meg. The aforementioned Graham stars as a sailor tracking down Gertrude’s progress, Ecclestone as her trainer, and Clifford as her swimming instructor.

They are joined onscreen by Kim Bodnia and Glenn Fleshler.

What are people saying about Young Woman And The Sea?

Speaking to Clutch Points about what it was really like to film those all-intensive swimming scenes, Ridley explains: “I think the run-up to the big swim was probably the most difficult time because we had done most of the film already, so I was already tired and we had already done a lot of swimming. So physically [and] emotionally, I was tired. And then I was trying to keep my mind on what we were filming while knowing that I had to prepare for nine days in the sea.

“The build-up was almost worse than the thing, but then there were moments where I thought, How am I going to do this? How am I going to come back tomorrow and do this and the next day, and the next day?”

To help with the stress, Ridley added that she found a wealth of support in the cast and crew: “There were lots of deep breaths, lots of distraction games, and lots of playing music, and staying warm in between times. And honestly, hanging out and being silly.”
