Przekładaniec is a 1968 short science fiction comedy film directed by Andrzej Wajda based on the screenplay by Stanisław Lem, which was a loose adaptation of Lem's 1955 short story turned into a radio play Czy pan istnieje, Mr. Johns? (Translated into English as Are you there, Mr. Jones?). The title of the film was variously translated into English as Layer Cake (literal meaning), Hodge Podge, or Roly Poly. The first print of Lem's short story was in Przekrój in 1955. Translated as Are you there, Mr. Jones? it appeared in a British-Australian science fiction magazine Vision of Tomorrow in 1969. According to the introduction to the story in the magazine, it was the first work of Lem translated into English. The central idea of the film concerns the problems related to organ transplantation, namely, what is the legal identity (and the associated legal rights) of a person whose body includes many transplants and that of a person whose body was used for many transplants? The film is a rare example when Lem was pleased with an adaptation of his work. Lem wrote that Wajda's film was the only adaptation of his works which had satisfied him (Lem) completely. Lem even confessed that he had found the course of the events in the film to make more sense than in the short story. Plots Wajda's film is the story of two brothers, Richard Fox, rally racer, and his brother Thomas, who had terrible car accidents. In the original Lem's work they were Harry Jones, a racer after series of car accidents, and his unnamed brother, who suffered a plane crash. Radio-play version In this version, the dilemma is posed in the domain of advanced prosthetics bordering with robotics. Harry Jones has a series of grave accidents, after each of which Cybernetics Company adds prostheses to his body until virtually all his body, including a half of his brain, becomes artificial and Jones accumulates a huge debt to the company. The company sues him for return of all prostheses, but the lower court rejected the claim because it would be equivalent of killing Jones. The company tricked him into replacing the remaining half-brain and then sued with the demand to acquire Jones as its property in lieu of debt. The court is confronted with the dilemma: if Jones is machine, he/it cannot be sued, otherwise, if he is still a person,
