Born in Prague, Czechoslovakia, Geislerová's rise to national fame began at the early age of 14 when she debuted in Filip Renč's Requiem pro panenku in 1991. Since then, the country has followed her career closely, watching her metamorphose into the Czech Republic's most recognised Celebrity on the small and silver screens. Her numerous acting credits include Academy Award winner Jan Svěrák's Jízda in 1994 as well as the film adaptation of Michal Viewegh's internationally acclaimed novel Výchova dívek v Čechách (1997).
