 Roman Polanski (qv) had intended to take on the role of the young  hitchhiker himself, but Jerzy Bossak, head of the Polish film unit  KAMERA (under whose auspices the film was made), turned him down  because he didnt consider the director attractive enough. The  characters voice, however, is Polanskis, who later dubbed the part  over. Zygmunt Malanowicz (qv) had a strong, developed, bass voice,  which was quite inappropriate for the character.
