Other notable actors "in the RAF" so to speak, are Richard Attenborough, David McCallum, and Charles Bronson, who plays what would appear to be a Czech RAF volunteer. Being 1944, most of the Eagles had transferred to the USAAF by this time, so the Henley character must have been in the camp for quite some time, or else was one of the few who refused to switch into the Army Air Corps. The former is more likely as his service dress suggests a much earlier period of the war while most of the other men wear battlejackets indicative of the post-Battle of Britain period.
Details aside, this is easily one of the best war films ever made.
James Garner as "Henley," an American volunteer for the RAF and the camp scrounger in the film. Note the "USA" patch on his shoulder.
Richard Attenborough as Squadron Leader "Bartlett," the head of the escape team, seen here with "Griff," the disguise tailor. Note Attenborough's "battledress" uniform as compared with Griff's earlier "service dress" uniform which was often used during missions before the battledress came into being.
