The '60s was a time of socio-political change, and cinema began to reflect that change with buoyant films like Barbarella and ground-breaking films like 2001: A Space Odyssey. It was an era of true space exploration, and the sci-fi genre began to strive for authentic investigation of the cosmos. The Apollo 11 mission occurring in 1969 sent sci-fi into uncharted territories of imagination.

While films like Planet of the Apes dominated the box office with big stars and big budgets, there were no shortage of films that explored similar moral and ethical quandaries like The Time Machine. Cinema magic was being created using better visual effects and better camera maneuvers - creators had come a long way since using lizards to represent aliens. These 10 sci-fi adventure films of the era may have been forgotten, but there's still as exciting as they were in the '60s.

Fantastic Voyage Movie

When scientist Jan Benes discovers a way to shrink humans and objects, he's placed in the middle of a power struggle between communist Russia and the United States. Benes is smuggled out of Russia by the CIA, but he's attacked before he can complete the journey.

With a blood clot attacking his brain, time is running out, resulting in a nuclear sub with an American team on board being shrunk down to the atomic level and injected into his body.
