electricity

His masterpiece 'Metropolis' presents electricity and technology as central to dystopian urban power structures and social control.

His films obsessively explore electricity's intersection with the human body, most notably in 'Videodrome' and 'eXistenZ' where electrical signals merge with consciousness.

He contemplates electricity and technological progress as spiritual threats to humanity, particularly in 'Stalker' and 'Mirror' where technology reflects existential alienation.
