Golf and prison life were two fertile subjects for comedy (Laurel & Hardy used both motifs, the latter more than once). In Convict 13, Buster Keaton neatly kills two birds with one stone.
The movie begins with Buster as a golfer, and with a surprising twist on his physical dexterity. Usually, Keaton performs his physical comedy with subtle grace. But in golf, that most frustratingly intricate of sports, Buster never makes a simple miss at the ball; every time he swings, he flies around in full-circle twice before landing on his fanny, as though his golf club was a ball-and-chain he was slinging around. This proves to be an appropriate metaphor when, at one point, Buster gets knocked out and an escaped convict trades clothes with him. (Instant Prisoner – just add uniform.)
It turns out that the warden’s daughter (again, the resourceful Sybil Seely) is the girl on the “outside” whom Buster was trying to impress with his mediocre golf skills. Despite Sybil’s efforts to prevent Buster from getting hanged as a prisoner (resulting in a long-shot sight gag that’s astounding, even for Keaton), Buster proves to be far more adept in prison than at golf. Twice, he manages to thwart prison riots – the second time by using his ball-and-chain skills to subdue potential escapees with nothing more than a medicine ball. Many film historians have compared the iconic images of Keaton and Chaplin to little Davids conquering the big Goliaths; here you actually see Keaton doing it, and it’s immensely satisfying.
Considering the many unfortunate racist jokes that turn up in Keaton’s work, it’s also kind of nice to see Keaton’s black caddy get a laugh on him for a change (when Buster knocks a golf ball into a nearby pond and actually goes swimming to find it). Funny how Buster is more adept and physically looser in a perilous situation than he is at a sport where he should be having fun.
