Overview
The Unknown is a 1927 American silent horror film directed by Tod Browning, and starring Lon Chaney as carnival knife thrower "Alonzo the Armless" and Joan Crawford as his beloved carnival girl Nanon. Originally titled Alonzo the Armless, filming took place from February 7 to March 18, 1927 on a $217,000 budget.
The film carried the tagline: "A superb mystery thriller, unusual and startling even for a Chaney film. Lon as "The Unknown" eats, drinks, shoots a rifle and dresses with his feet. Don't miss this startling spectacle!"
Stills exist showing Chaney made up as Alonzo the Armless.
Plot
"Alonzo the Armless" is a circus freak who uses his feet to toss knives and fire a rifle at his partner, Nanon. However, he is an impostor and a fugitive from the law. He actually has arms, but keeps them tightly strapped to his torso, a secret known only to his midget friend Cojo. Alonzo's left hand has a double thumb, which would readily identify him as the perpetrator of various crimes from his past.
