Mr. Sardonicus (1961, U.S.A.)

Desperate to retrieve a winning lottery ticket, a greedy baron unearths his father’s corpse. An enormous jackpot is his reward, but not without a price: his face is frozen permanently into a hideous grin. He enlists his fiendish one-eyed servant to help him lift this horrible curse, but their schemes fail. Finally, he turns to a noted neurosurgeon – and his wife’s former lover – to cure him.
