In the following years he played in a number of theatres, both in the capital city and in other places throughout the country, as well as in many feature films. He is winner of the best actor award of the "Golden Prague" TV films festival (1982).
His best loved character on the scene is the big Little man - a human being incessantly trampled by Life and the high and mighty, who frequently evokes laughter, but more often the sympathy and compassion of the audience - because of the nobleness, dignity, modesty and selflessness always helping him managed and overcome the vicissitude of his destiny.
