Val Guest was such a master of this material. The sequel to the original. Enjoy this a lot, the moonbase location and the rare performance of Sidney James in a serious role make this a stand out classic.
An almost completely different animal than its predecessor. A lot of unnerving imagery with a slightly more disturbing story make for a much better sequel. Not much in the way of monsters but by the time they get loose its a hell of a good time. Not too much of a Hammer sci-fi fan, but Quatermass 2 is definitely an exception.
