A Man Changes Skin (Russian: Человек меняет кожу, romanized: Chelovek menyaet kozhu) is a 1960 Soviet mystery drama film directed by Rafail Perelshtejn.

Two Americans come by contract; a grizzled spy Colonel Bailey (Boris Vinogradov), who introduces himself as a harmless traveler by the name of Mr. Murray, only later to be caught red-handed and unmasked, and Mr. Clark (Sergei Kurilov), who arrives to the canal to "make money" and gradually becomes convinced that work and politics are not that different concepts.

Love for the Komsomol translator Maria Polozova (Izolda Izvitskaya) helps Clark to comprehend what is happening.

In the middle of the construction is the engineer Urtabaev (Gurminch Zavkibekov), a strong, bright man, one of the first representatives of the Tajik intelligentsia.

On the festive opening day of the canal the last Basmachi gang is defeated in a fight which kills Komsomol leader Karim (Djakhon Sidmuradov).
