Original owner – Josef Jandáček (1883–1952). An outstanding photographer, advocate of cinematography, and one of the founders of Czech film distribution. The building was constructed according to plans by Vojtěch Puč, a well-known architect living in Břevnov.
On December 23, 1930, the opening screening of the new venue, named BIO IDEAL, took place here with a showing of the Czech-American film *The King of Jazz*.
The interior was very modern. The cinema had over 400 seats and was equipped with a buffet, a coat check, large restroom facilities, a smoking room for men, and an efficient steam heating system throughout the building.
BIO IDEAL remained one of the most popular cinemas in Prague for a long time, even during the war. It hosted both regular feature films and screenings of newsreels, which allowed people to learn about distant parts of the world they had never had the chance to see themselves, and these screenings were accompanied by extraordinary musical performances. In August 1945, however, the so-called “Decree on Film” was issued, under which all establishments of this type were nationalized. Only the state was permitted to rent out and publicly screen films. In 1948, the cinema was renamed “RADOST.” Until 1992, it was operated by the Prague Film Enterprise, and this cinema ranked among the 50 most-visited venues in Bohemia and Moravia.
