(1969, Patrick Allen, George Sanders, Neil Connery)

Utterly feeble British science fiction horror, enlivened by a performance by the RAF's Red Arrows display team in the days when they flew Folland Gnat trainers, and a roofbox RT hurtling through Whitehall on route 77, while two others pass in the other direction. The aliens' spaceship, improbably, is the Daleks' craft from 'Daleks: Invasion Earth 2150. Sadly it looked like a flying chamberpot then, the special effects are so poorly deployed in this film that it doesn't even fly.
