LONDON - The first day of filming on a new production is a nerve-jangling time for any actor, though few will ever experience the fear that beset Felicity Jones and Eddie Redmayne on the set of The Aeronauts. The English actors were involved in a balloon crash that could have easily claimed their lives.

"It was frightening," says Jones in London. "We had got the shot and all we had to do was come down, which we thought would be the easy bit."
