Mariánské Lázně and Karlovy Vary used to run a joint festival, and in the first year, 1946, the bulk of the films were shown in Mariánské Lázně. However, after 1949, screenings there stopped. The festival continued in Karlovy Vary, and this year marks its 57th edition. If the numbering seems off, that is because for a while it was held every other year, alternating with a festival in Moscow.
