Stephen Swain studied production design at the National Film and Television School in Beaconsfield between 1998 and 2000. Following this, Swain began his film career working with Stuart Craig over a ten-year period on the Harry Potter series of films. Years later, as an art director, he continued his professional development, learning from many prominent designers with the same strong focus on drawing, model making, and architecture. This accumulated knowledge has allowed Swan to recognise and appreciate how good design supports and enhances the telling of a story.

In the early stages of his career, Swain spent a number of years working as a standby art director. In this role, he gained vital first-hand practical experience, collaborating closely with other departments during the filmmaking process.

Stephen Swain is a member of the Art Directors Guild (local 800), BAFTA, and a fellow of the RSA.
