This is the trailer for the 1969 Japanese-American sci-fi adventure starring Joseph Cotton (‘Citizen Kane’, ‘The Third Man’, ‘Dr. Phibes’) and Cesar Romero (Joker from the 1960s Batman series). Produced by the same film company (Toho) that made all those Godzilla movies. Although this movie is somewhat cheesy, it is very entertaining and it shows that movie-making does not have to be taken seriously.
