"Zombie Lake" immediately comes to mind for me. The movie may not be all that high on the exploitation scale, but I love the scene near the beginning of the film where the girl is swimming in the lake. Very hot! I also love Ursula Andress in "Slave of the Cannibal God."
Ah,
Zombie Lake. That's just a fun movie.
Never got into the cannibal sub-genre yet, somehow, I ended up with two DVDs of Slave of the Cannibal God. I thought it a bit slow at times.
