Like much of the famously cranky Kneale’s legendary TV output, the Quatermass scripts largely concerned themselves with smart people thinking their way through potentially apocalyptic problems, often while being bedeviled by obstructive bureaucrats and general, low-level idiocy. Although they’re relatively poorly known in the U.S., the various Quatermass projects are a fundamental part of the DNA of British genre TV, influencing any number of shows and films, and especially the early incarnations of Doctor Who.
