Oh, scifi movies definitely hit the A-List after Star Wars
and Close Encounters
, but I always like to remind people that, you know, movies and fandom existed before 1977. (This is, I admit, something of a hobby-horse of mine.) And I seem to recall there being more than twelve hardcore fans just in Seattle back in the day!
Plus, the studios occasionally dabbled in A-list "prestige" science fiction pictures beyond Forbidden Planet. I'm thinking films like 2001, The Andromeda Strain, Fahrenheit 451, The Illustrated Man, Silent Running, Planet of the Apes, The Omega Man, Soylent Green, and maybe even Logan's Run.
Although, of course, these were wildly outnumbered by drive-in B-movie stuff like The Land That Time Forgot and The Green Slime.
(This concludes our trip down SciFi Memory Lane.)
