This was an extra on the Hollywood Cavalcade DVD. In the movie, a heavyset man is walking on a movie set and is seen from behind. Someone on the set greets him by saying, "Hi, Roscoe!" That man walking on the set is supposed to represent Roscoe "Fatty" Arbuckle. The woman who discusses him on the extra mentions his three trials for manslaughter of which he would eventually be exonerated but the public seemed to turn against him as Buster Keaton discovered when he met his former mentor at the train station and saw the unruly crowd there. She then discusses his return to vaudeville, his turning to just directing, and then a comeback to making shorts for Vitaphone-which was owned by Warner Bros.-before signing for a feature contract before dropping dead just after that. If you want details on the man's life and career, this too-short extra isn't recommended but it provides enough info to anyone a little curious about this once-popular comic.
