What was/is your fav Sci Fi movies pre-1968 ?

[thunderbolt]

The Thing(even though its really a Universal Horror movie in disguise), Them!, It Came From Outer Space, Godzilla, The Man From Planet X(another Universal inspired movie), Invasion of the Saucer Men, Colossus of New York (even more Universal style), Village of the Damned. The Thing and Man from Planet x really bridged the change from 30s-40s horror to 50s SF movies.

[The Bat]

King Kong
The Valley of Gawangi
20,000 Leagues Under the Sea
The Creature from the Black Lagoon(I consider it more Si-Fi than horror)
