Donald
He makes it watchable;
-of course Buster was one of the all-time greats !
Just watched the film again and O'Connor does a credible job of attempting to emulate a screen legend who had extraordinary physical skills which put the onus on Don-yet he did well.
Fun to watch Lorre and Blythe-and Anne is just plain lovely and demur in the part.
Historically there are holes,but they(Paramount)tried to capture the essence of what Keaton was all about.I think it was certainly gargantuan a task-but kudos for the ole college try !
Plus I think Buster himself liked O'Connor and his efforts to do justice to his own physical comedy from his own silent films. I say that from seeing Buster's warm reception to Donald on "This Is Your Life-Buster Keaton (1957)" (one of the few high spots in one episode of what could have been such a fun series were it not for the obnoxious and definitively unfunny host).
If all I could see from this movie is O'Connor's recreation of some of Buster's silent film scenes, I'd watch it. But I'm afraid that the horrible (and inexcusable) inaccuracy of the film overall keeps me from watching it enough to just edit out and save these good parts. Buster WAS a consultant on the film, but the results show it was apparently in name only as Paramount didn't pay any regard to his input (but I think Donald did).
I can only thank God that Buster ended up being one of the most famous and beloved of all comedians while he was still alive to see it, in effect getting the last laugh over all his detractors and nay-sayers. :-)
