The pair previously co-starred in James Marsh’s romantic drama, The Theory of Everything, which depicted the marriage of Stephen Hawking and his first wife, Jane. Their performances in The Theory of Everything earned Redmayne an Academy Award for Best Actor and Jones a nomination for Best Actress.

The Aeronauts, which began shooting in the U.K. this week, is a period drama set in 1862. The film follows the wealthy young widow Amelia Wren and scientist James Glaisher, played by Redmayne and Jones respectively, as they undertake a hot air balloon expedition to fly higher than anyone in history.

One of the producers working on The Aeronauts, Todd Lieberman, praised the duo for taking to the skies themselves for the scene.

“This image was taken after we launched Felicity and Eddie 2,000 feet in the air, performing their scripted scene, while a helicopter captured it all. We’re fortunate that Felicity and Eddie have the nerve to do these stunts themselves as it authenticates our entire approach.”

Lieberman also said: “A top priority for us on The Aeronauts is authenticity. With that in mind, we intend to do as much balloon filming in the sky as the weather will allow.”

The Aeronauts is directed by Tom Harper, best known for his work on Peaky Blinders, and written by five-time BAFTA winner Jack Thorne, who wrote the stage adaptation for Harry Potter and the Cursed Child.
