Not just one invasion, but several!  At least you get your money's worth.

So... the Forces from the Black Void have fairly simple-looking flying saucers and astonishingly appalling dress sense.  But at least they can "communicate with time", whatever that means.

This was released about six months after Star Wars - It's not hard to see why Starship Invasions disappeared in the shadow of it.  Those silver 'robots' would have been an embarrassment at a school play.

Apparently Christopher Lee plays the villain in this.  Pity they didn't show him in the trailer (unless that's his eyes 15 seconds in).

Favourite bit:  The robot falling down the shaft.
