I loved the Invaders on TV in the 1960s. It ran for only two seasons here but was more popular in Europe. Roy Thinnes knows the invaders are here to take over their world. Their OWN planet is dieing. The Invaders seem to have spontaneous combustion, so there's no proof that they were here. Look out for someone with a pinky in the air--could be one of them! The concept of the series is possibly a metaphor for something else and I am glad to see reruns of the show on METV. We just saw episode 3 at 5 a.m. Roy Thinnes is convincing as the main character, and the show has some famous guest actors.
