“The Mack Sennett Keystone comedies were the culmination of
15 years of comic primitivism—the characterless jest and the excitement of
motion raised to the nth power” (Mast 43). Before Sennett, American film comedy
had been confined to the music hall sketch; he gave it the freedom of
destructive absurdity. While still
at Biograph, the future King of Comedy moved Griffith’s static, inert,
indoor-bound camera outside, where it enjoyed both visual freedom and the
freedom to move. And move it did, at mad speed, nearing supersonic velocity,
stopping only when the figures onscreen smashed through one wall too many, fell
down manholes or wells too deep, or were simply overcome with exhaustion The
filmmaker added tremendous energy and breathtaking pace, the incongruous and
the non sequitur, and a taste for burlesquing people, social custom, and the
conventions of other films.
Hal Roach was always second to Sennett; the latter
established the formula while the former merely adopted it. While Roach began
imitatively, copying Sennett’s chases, falls, custard-pie throwing, and
generalized chaos, he gradually began thinking more in terms of character than
non sequitur, carefully structured gags instead of speed, logical plotting
rather than constant, cumulative romping. Roach’s films benefited from more
structure, less improvisation, creating what Gerald Mast calls a perfect
stairway to insanity (185). To use the same metaphor, Sennett did not ever take
the stairs up; he took the elevator, punched the floor button—or, if feeling
especially inventive, whacked it with a hammer—got stuck a couple of times
between levels, sometimes plummeted, coming close to the bottom of the elevator
shaft, and, finally, shot through the roof.
