Composer David Arnold tells Justin Johnson why he loves You Only Live Twice, the first James Bond film he saw on the big screen. He discusses his scores for five later Bond movies, and his new project -- a musical version of the film Made In Dagenham. This event formed part of the BFI's members' only Screen Epiphanies strand, presented in partnership with American Express: http://www.bfi.org.uk/bfi-membership.
