He was the voice of Lampwick in Walt Disney’s Pinnochio (1940), the bad boy who gets turned into a donkey on Pleasure Island, maybe the most upsetting scene in any Disney cartoon. He was one of two actors inside Robbie the Robot in Forbidden Planet (1956), small enough to fit inside the costume. He played lots of jockeys and Dead End Kids and Bowery Boys, and he made scores of low-budget westerns. He was menaced by Boris Karloff in The Mad Genius (1931). He was a man in a leg cast hoisted up in his hospital bed in Blake Edwards’s The Perfect Furlough (1958) and he examined Cary Grant’s posterior in Edwards’s Operation Petticoat (1959). As an adorable, Jackie Coogan-like little boy, he got a laugh asking a woman to dance in Flesh and the Devil (1927) right before Greta Garbo waltzes away with John Gilbert. He was a son to Marie Dressler’s Tugboat Annie. On Red Skelton’s TV show in the 1950s, he did an old lady routine that routinely brought down the house. Frankie Darro had a long and varied career. And in 1933, in two films, Mayor of Hell and William Wellman’s Wild Boys of the Road, Darro is an actor with a capacity for greatness, if anyone had bothered to notice.
