According to
Fernsehen
der DDR, the German adaptation of Lem’s script finds the science-obsessed Professor
Tarantoga with a strange guest who calls himself Novak (or maybe Hipperkorn) and claims to
hail from fourth-millennium Mars where he quulles. part from the bit about quuelling, this
certainly sounds like the 1963 Polish script that we read, but we don't know whether it was
expanded or revised.
