||As a favor to long-time friend William Walton, Arnold agreed to orchestrate Walton's score for Battle of Britain (1969). When Walton found difficulty composing under the schedule at his age, Arnold secretly helped compose several cues. Ultimately, however, the score was rejected and replaced with one by Ron Goodwin. The Walton/Arnold version of final battle scene score, however, was retained in the release version. The Walton/Arnold score has since been released on CD and as an alternate track on the M-G-M release of the film on Blu-Ray and DVD. Arnold's contribution is unmistakable to those familiar with his style.
||The producers of "Bridge on the River Kwai" wanted to release the movie in time to make the deadline for Academy Award consideration. However, they couldn't find any composers willing to write a score on such a tight deadline. Arnold accepted the challenge. They gave him 10 days to compose the complete film score; he did it, and won the Oscar for best score.
