Query: when critics once wrote about science fiction as silliness, movies like this only fed them fodder

a generation after "destination moon", and a year after "2001", this was the type of garbage that hollywood still was turning out and branding as "science fiction". obviously made to capitalize on that years moon landing (but before the next years eerily similar apollo 13 mission), this cannot be a bright spot on the resumes of actors like gregory peck or gene hackman or richard crenna (as for david janssen, hey, who cares?). rent some buster crabbe for a better plot and better effects.
