Some I know of are:
Link (Underrated Richard Franklin (Psycho II, Cloak and Dagger) film)
Monkey Shines (Decent George Romero film also about monkeys)
Alligator (Not familiar with it, but from director of Cujo)
Mosquito (Lame direct-to-video film)
The Birds (Classic Hitchcock fare)
Squirm (MST3K episode, so it has a so bad it's good quality to it)
Piranha (Solid Jaws spoof from Joe Dante)
