Never realized how some of you guys are just youngsters!
First seen (from complete to end) Monster Zero in 1974 (KTLA Channel 5, showed it for a full week on prime time!)
First owned - going on a technicality, Ghidrah, The Three-Headed Monster,
but in 8mm form that my folks bought for me at K-Mart back in the mid 1970s. However, Ghidrah, would also be my first owned VHS (from Video Treasures) that I bought around 1989.
First sub - Godzilla 1954 (bootleg)
Theatrical - Godzilla vs. Megalon, Labor Day weekend 1976 (which I also saw on a double-bill with the original King Kong, in a theater that is now
long gone).
