What is your favorite cheesy, grade "B" SciFi/Fantasy/Horror movie? We all have one, but oftimes don't admit it.

Mine is "Attack of the Crab Monsters", Directed by Roger Corman. It's a classic Post Nuclear Age "What hath Man wrought?!" story about mutated land crabs that destroy two research teams sent to study the aftereffects of the Bikini Atoll Atomic Tests.
Bonus: It stars Russell Johnson (The Professor from Gilligan's Island) as the regular guy who saves the day!

Lord of the Rings (the really old cartoon one).

"THEM" starring giant killer ants!

Fantasy: Hawk the slayer
Sci Fi: Flash Gordan (You know the cheesy one with music by Queen)
Horror: Id have to go with Zenith and say Them

Memnoch: They guy who did the animated lord of the rings did another fantasy 'toon called "Fire and Ice" check it out, its pretty good. Frank Frazetta put up the funds to make fire and ice to those of you that means anything to!

'Ladyhawk' with Rutger Haure (?spelling?). It also had the guy from 'Ferris Beuller's Day Off' as the thief. The girl was cursed and spent most of her time as a hawk. I don't remember the details, but R.H. was a badass with a broadsword and a huge warhorse.

'Lady-hawk' update:
The music was done by Alan Parsons Project. (Also Awesome) This is a great rent.

Further Lady Hawke update:
They you guy from ferris beulers you were thinking of Magnus is Mathew Broderick. I do believe the female lead is Michelle Pfiefer in an early role!

(For another Cheesy (but good) Rutger Hauer Hire "Salute of the Jugger")
