The 21th Locarno Film Festival was held from 26 September to 6 October 1968 in Locarno, Switzerland. There was fight on the festival jury this year. Due to the invasion of Czechoslovakia by Warsaw Pact countries, Czech director and jury member Jiri Menzel refused to vote on films from Warsaw Pact countries as he felt he could not fairly evaluate them. As a result, the five person jury voted to ask the distributors of films from the Soviet Union, Hungary and East Germany to remove them from competition at the festival. However, after the vote, two jury members, Michel Cournot and , thought this was too extreme and threatened to resign, while jury members Puriša Đorđević and André Delvaux sided with Mezel. The result was the selection of an entirely new jury, pulled from the youth jury, and all films were again considered in the competition. Also, like at other festivals this year, student protesters briefly interrupted the festival during the last night, but ultimately did not stop the festival for long. The festival's top prize, the Golden Leopard, was awarded to "The Visionaries" directed by Maurizio Ponzi. Official Sections. The following films were screened in these sections: Main Program.
