Eu acho que você pode estar falando sobre a adaptação de 1989 de Difícil de ser um Deus . Não consegui encontrar um bom resumo da adaptação de 1989, mas o artigo da Wikipedia para o remake de 2013 abrange os pontos altos e o site do livro que eu relacionei acima mencionam a imprensa.
A group of 30 scientists travel from Earth to a nearly-identical alien planet that is culturally and technologically centuries behind. The inhabitants of this planet have brutally suppressed a renaissance movement, murdering anybody they consider to be an intellectual, and thus the planet is stuck in the middle ages. Anton, one of the scientists from Earth, is sent to infiltrate the local populace of the Kingdom of Arkanar and help them progress as a society, although he is forbidden from getting involved with local politics or forcibly interfering with the advancement of technology or culture. He assumes the identity of Don Rumata, a nobleman who resides in a large castle surrounded by poverty. There, he lives with Ari, a young woman whom he has taken as his bride, and the juvenile prince of Arkanar. Rumata's presence divides local opinion; some treat him as a God, others despise him.
