He can be easily spotted doubling for Errol Flynn in
The Adventures of Robin Hood (1938). When
Robin Hood escapes into the crowd after the archery tournament, his
"disguise" is so effective because he's played by Buster rather than
Flynn. A DVR recording of the TCM broadcast of the movie, viewing the scene in slow motion, is required to see him. A DVD recording cannot be played in slow motion smoothly enough to be able to spot him.
