"Director Coleman Francis uses edits like blunt instruments. He uses blunt instruments like blunt instruments. His major themes are death, hatefulness, death, pain, and death. He looks like Curly Howard possessed by demons from Hell. He tried to pass off Lake Mead as the Caribbean Sea. His films have the moral compass of David Berkowitz. He hurts us and I want him to know it, except if he's still alive, because there's the small chance that he's still strong enough to crush my windpipe with his bare hands."note

"Any discussion of Red Zone Cuba would be remiss without a mention of its writer, director, and star, Coleman Francis, who's also singlehandedly responsible for two other cinematic abominations, The Beast of Yucca Flats and The Skydivers. (...) Probability dictates that every now and then, a totally clueless director like Hal Warren or Tony Malanowski might punch through and end up making one of the worst movies ever just by pure chance, but to make three of them clearly requires active hatred towards paying audiences."
