Arbuckle's problem is that the Virginia Rappe affair occurred Labor Day 1921....and he very seldom appeared onscreen after that. Note that 1921 conveniently is just before the 1923 cutoff for copyright, meaning virtually all of Arbuckle-starring films are in PD status and it takes a special effort to restore and present such films knowing they may be copied mercilessly by the less scrupulous.
Does anyone know if his, I believe, 6 final starring role talkie short films survived? I heard words about them in the commentary, but I reckon they either aren't PD and/or are seemingly totally lost.
True, but it also conveniently means that Arbuckle's films aren't controlled by a studio like Paramount, who'd sit on them and do absolutely nothing with them, like all the existing silents they currently control. So, entities such as the good people at Laughsmith can gather prints from archives and collectors and make that special effort and put them out for the fans to enjoy.
I wish all of Paramount's silents were owned by Warner Brothers instead.
Mr. Laughsmith himself, Paul Gierucki, posted over at the Silent Comedians board that, though their releases are currently out-of-print, they will be coming back into print, and better than ever. He didn't say exactly when, however.
