There were a number of adaptations of Stanislaw Lem's works. These include films such as The Hospital of Transfiguration, The Astronauts (First Spaceship on Venus), The Investigation, Roly-Poly, Solaris (filmed twice: in 1972 by Tarkovsky and in 2002 by Soderbergh). TV adaptations include Pirx kalandjai (Hungary), The Test of Pirx the Pilot, Victim of the Brain (Seventh Sally), Ijon Tichy: Raumpilot (2007).
