Above all, Helena Růžičková was known for her comedic talents, and for films produced in the Czech Republic and East Germany.
She became popular especially thanks to her roles in Jaroslav Papoušek's comedy trilogy about the Homolka family (1969-1972), and in another comedy trilogy Slunce, seno... (1984-1991) directed by Zdeněk Troška.
