The Jára Cimrman Theater staged its first premiere exactly 50 years ago, on October 4, 1967. Its members celebrated the half-century anniversary with a special program that included scenes from plays by the trio of authors Cimrman, Smoljak, and Svěrák, which have since become cult classics. Psaní do nebe (Writing to Heaven) is a letter written by Zdeněk Svěrák to his long-time friend and colleague Ladislav Smoljak in connection with the 50th anniversary of the Jára Cimrman Theater. It became the backbone of the entire gala evening at the Žižkov Theater. The performance also included excerpts from productions and a number of other items.
