I caught this on Prime under the title BOA. It's a typically cheesy monster flick with an elaborate set-up which isn't particularly convincing at any point. The story is about a high security prison in the Antarctic (!) of all places, with action man Dean Cain (yes, Superman himself) playing the macho lead. A giant boa constrictor is released into the confines of said prison and eludes all attempts at capture and/or destruction. The CGI effects are very bad indeed, and there's nothing doing as regards the performances and scriptwriting; it's all rather tired and bland, I'm afraid.
