His films frequently explore human communication and isolation, particularly in 'Fitzcarraldo' and 'Aguirre,' where radio and distant contact represent humanity's fragile connection to civilization.

His masterpiece 'Playtime' and other works satirize modern communication technology and human disconnection in an increasingly mediated world, with radio and broadcasting as recurring visual motifs.

In 'Stalker' and 'Solaris,' he explores communication across vast distances and the limitations of transmitting meaning between worlds, using radio signals and dialogue as metaphors for human longing.
