"Remember, no matter where you go… there you are." This week on Journey Through Sci-Fi, we're looking at two very different visions of genius at work - one saving the world, the other stealing dreams. We discuss The Adventures of Buckaroo Banzai Across the 8th Dimension (1984) - now say that five times fast - and The City of Lost Children (La Cité des enfants perdus, 1995) to explore the heroes and villains of mad science.
