Three Fat Men (Russian: Три толстяка, romanized: Tri tolstyaka) is a 1966 Soviet children's fantasy film directed by Aleksey Batalov and Iosif Shapiro based on the eponymous novel by Yury Olesha.

A traveling caravan of performers, including the clown Augustus, the acrobat Tibul, and the young girl Suok, arrives in the city just as a miners' uprising erupts.

Suok, posing as the repaired doll, is delivered to Tutti’s chambers, where the lonely boy discovers her secret but chooses not to expose her.

Suok retrieves the key to the royal prison and frees Prospero, but her deception is revealed when the real doll is found elsewhere.

As the execution looms, Tibul and the rebels infiltrate the palace through an underground passage, sparking a second uprising that overthrows the Three Fat Men.
