Must-see movies are futuristic classics that shouldn't be missed. Of course, not every must-see is perfect. That's why we've rated them 1-5 on the patented "crunchy goodness" scale.
Title: Donovan's Brain
Vitals: When evil millionaire Donovan suffers a fatal car crash, mad scientist Dr. Cory rescues his still-living brain to see if he can keep the organ alive in a fish tank. Things go awry when Donovan's brain starts to grow telepathic powers, taking over Dr. Cory's mind and forcing him to make ruthless investments.
Famous names: Nancy Reagan
Crunchy goodness: 3
