The Computer King (1989)

Marcin is an exceptionally gifted child - a computer genius. The enigmatic "Computer King" has therefore set his sights on him. He resides in the netherworld where he exercises his power over famous deceased scientists and artists. He's going to use them to snatch the young programmer away from the real world and into his own kingdom. Now every machine Marcin comes across may well be a bringer of his doom.
