Na vsyakogo mudretsa dovolno prostoty), sometimes published in English under the title Too Clever By Half, is a five-act comedy by Aleksandr Ostrovsky.

A production of the play was the most significant of the early theatre work of the Russian Soviet film director Sergei Eisenstein.

[5] The playwright Sergei Tretyakov transformed Ostrovsky's text into a revue (what Eisenstein called a "montage of attractions"), which was entitled Wiseman (Mudrets).

[6] Eisenstein and Tretyakov's approach was part of the Russian avant-garde Futurist movement known as "Eccentricism," which sought the "circusisation" of the theatre.

[9] Eisenstein drew on popular theatre techniques such as farce and the commedia dell'arte in his staging, which sought to make every metaphor concrete and physical; he wrote:[10] A gesture turns into gymnastics, rage is expressed through a somersault, exaltation through a salto-mortale, lyricism by a run along a tightrope.
