They Saved Hitler’s Brain (1964)

At the end of World War II, Nazi officials spirited the living head of Adolf Hitler out of Germany to a hiding place in the South American country of Mandoras, in order to revive the Third Reich at a later date. By the 1960s these men believed the time had come, so they kidnap a top scientist in order to force him to help keep the brain alive. Several intelligence agencies find out about the plot and send agents to stop it.

This film was re-edited from the movie Madmen Of Mandoras (also available here at Rare Movie Collector) with additional sequences reportedly shot by film students.
