Building The Mammoth - Featurette for The Aeronauts

"Much of the film is just two of us in this tiny space. How do we
make the balloon the other character?" - Eddie Redmayne

"September 1862 James Glaisher went up in this amazing balloon the Mammoth,

which has been reproduced brilliantly here. It's exactly as it was."

- Richard Holmes, the author of 'Falling Upwards' 

(a wonderful book about the 19th-century aeronauts) 

"We only do what is possible, so the audience will feel that they're experiencing
something that really happened." - George Steel Cinematographer
