Hilarious direct-to-video gem from the 80’s by B-movie maker Greydon Clark.  I still have to see Angel’s Brigade. 
I hear it’s great.

Anyhow, the demon cat effects are an absolute laugh riot. As well as the boat miniatures. And the talent in this film are way too good for its content. But George Kennedy, Alex Cord and the incomparable Clu Gulager are definitely not taking it seriously. And the two spring breakers played by Toni Hudson and Clare Carey are both great and way too hot for this film. Seems like both actors have had nice careers with Carey still doing a ton of work. 

Another wonderful retro discovery.
Watched the Vinegar Syndrome Blu-ray.
