More Movie Tricks

"Charlie Chaplin came into the studio when making "A Dog's Life" and wanting some papier-mâché cream puffs made up. He wanted imitations pastry light enough to be popped into his mouth by twos or threes. The result was a tray load of delectable-looking cream puffs that were detection-proof three feet away. When they were placed on the vendor's wagon, and the comedian begun snatching them into his mouth, the camera man did not know they were faked until told by the director to "cut" so that Charlie could spit out the pasteboard." - Picture Play Magazine, April 1919
I don't usually do this, but this has been on youtube. Chaplin's films from 1918 'A Dog's Life' onward, are copyrighted with Roy Export. But this does show the film clip the magazine article talks about.
And for you Charlie Chaplin fans out there, a special Charlie Chaplin Conference will be held in Ohio, October 28-30, 2010. You can learn more at this link.
