When the Woman Butts In (1960)

Miroslav Hornicek is a deluded young man who is convinced he is Faust incarnate. This turn of mind leads to some ludicrous situations, such as when he believes a woman is really a cat. Before he can be rounded up and interned wherever they keep people with this type of a problem, love enters his life and the clouds that obscured his vision begin to dissipate.
