Thanks to his impressive masculine stature, handsome face with expressive eyes, along with charming manners heightened by a pleasant and resonant voice he, at first, impersonated various lover characters.

As he aged, he began to adapt to more various roles, thus starting his career as a classical actor, appearing subsequently in plays of the Czech national literature and the world literature as well (Tyl, Jirasek, Vrchlicky, Langer, Sramek, Capek, Hasek, Sophocles, Lope de Vega, Molière, Flaubert, Strindberg, Rostand, Schiller, Goldoni, Gorkij, Balzac, Lermontov, Pushkin, Tolstoi, Shakespeare, at al).

In July 1937 he married a stage dancer Gertrude Nettel, with whom he lived till her death 57 years later and with whom he had two sons.

Shortly after the war he appeared in a title role in the film "Muzi bez kridel, alias Men without Wings, alias Les Hommes sans ailes", which was later honoured by the Golden Palm Award in Cannes Film Festival in 1946.

Seven years after his death, Pavlína Vajčnerova published in 2005 his biography titled Gustav Nezval – oči spíše sympatické.
