I'm thinking about some 50's B-movie films that I recall watching here's some that I remember:

Tarantula
Some early Roger Corman Movies - I remenber Leech Men/People?
Mole Men
Creature from the Black Lagoon
The Blob
Attack of the Monolith Monsters

How many still know "Day of the Triffids"?

there's more but I need to see some pix to remind me.
B-films are cool produced with no budget and no planning just out to make something. Of course they may not be palatable except to the crew!
