Quatermass and the Pit is a truly remarkable piece of television. An excellent script, brilliant atmospheric direction and great performances from the cast. Anthony Bushell's Colonel Breen is an utterly unlikable character without being a clichéd hissable villain figure. The guy is so uptight you can almost feel his buttocks clenching! Cec Linder is a very likable character and his friendship with Quatermass is totally believable. As for Quatermass himself... whilst Brian Donlevy played a totally different character (let's be honest the character in the first two Hammer movies is Quatermass in name only, or should that be'Quittermuss'?) John Robinon was really good in the role, Reginald Tate, Andrew Keir and John Mills were all excellent but Andre Morell makes the role his own and completely outshines all the other very fine actors who played this part. He's a charismatic figure full of charm, authority and compassion (if I was a scientist I'd like to be this guy!). Morell is totally convincing in all aspects of the role, whether arguing with pompous ministers or fighting the Martian influence he carries the whole thing along with considerable style. Rudolph Cartier creates a truly chilling atmosphere, complimented by the sinister incidental music. The design is also magnificent. The Martians were an inspired design and Hammer's version of the creatures ten years later are very poor in comparison. A brilliant piece of television science fiction, rarely (if at all) equalled in nearly fifty years!
