Watch The Interpretaris (1966) Official Trailer

An evil scientist, Parta Beno, who has been found guilty of imprisoning and reducing in size inhabitants of various planets. As punishment he is exiled to a remote asteroid, with the only amenities being a crude laboratory. All the specimens that Parta Beno collected were sent back to their home worlds by the World Council, except those few that the Council had no knowledge of, let alone any idea about the planets from whence they came. The hand-picked crew of 'The Interpretaris' were given the mission of returning these aliens to their home planets.
