top notch One of the very best British horror/sc fi films ever made,Hammer films had a strong feeling for Nigel Kneales works indeed the previous two Quatermass outings on TV had provided the basis for the first two Hammer films made with Brian Donlevy(an actor who Kneale hated for his limited acting skills).So some 10 years after the excellent Andre Morell had starred as the good Professor(who had of course already made several Hammer films )Hammer brought "Quatermass and the pit" to the big screen,using Andrew " I was in Dr who" Keir in the lead role,this was a much more understanding ,thoughfull,restrained and fully fleshed out Quatermass than Donlevy could ever hope to be(pleasing kneale far more);The budget of 450 grand or so was quite large by Hammer standards and this can be seen in a polished production with reasonable production standards(apart from fairly basic special effects undertaken by Bowie films).The film is generally thought of as the most faithful of the 3 large screen adaptations of the TV originals and was of course the first in colour,the casting of Juilan Glover ,Barbera Shelly ( another of the hammer rep company stalwarts) etc is spot on and all the cast add depth to the film in whatever role they play.The film itself is well paced and well structured with thoughtful ideas/concepts and is still thought provoking today.This is to be expected as Kneale dealt with interesting ideas/concepts through his long career( see "The wine of India", "The stone tapes" " "The year of the sex Olympics " etc).I recommend this film to all who enjoy good scripts/ideas of a horror/fantasy/sc fi feel without having to rely on over the top gore/special effects to provide a chilling concept,although the film itself did not provide Hammer with the return it was hoping for watch and enjoy(interestingly Kneale did submit a further script for Hammer for a 4th Quatermass film which they rejected,however this was the basis for the 4th outing on TV in 1979 with sir John Mills which so far has yet to be turned into a large screen outing,and Keir did play quatermass one last time on the radio in " the quatermass memoirs for radio 3 in 1996)
