This movie sees Brian Donleavy reprise the role of Bernard Quatermass,who when the movie opens is not a happy man,the British government having turned down his plans for a Moon colony.Distraction arrives in the form of objects from outer space landing in northern England .On going to investigate he finds a site looking more than a little like the moon project mock up,and to complicate matters his assistant(played by future author/director Bryan Forbes,then in his stalwart character actor mode)is stricken by on coming into contact with the alien substance and is carted away by the guards on the project
Quatermass gains entry to the plant as part of a parliamentary study group who are assured it is a project to manufacture synthetic food.Naturally ,they are being economical with the truth and the plant is the front for an alien invasion
How the intrepid if permanently bad tempered scientist tackles the problem is the root of the movie which still has resonance today in its suggestion of cover up and conspiracy,aliens having infiltrated the government and police(This would explain why British politicians seem determined that we shall be ruled by aliens--the EC!)
The movie makes good use of locations and the alien plant is an old utilities generation plant that looks chilling and strangely futuristic.Donleavy is too much on one note as,but Sid James is effective in a rare straight role as a hard drinking journalist and the rest of the cast are adequate
Special effects are antiquated.What still works are its atmosphere and sense of paranoia regarding our political lords and masters.
