UFO (TV series)
Only two of the alien suits were made, so at no point in the series are more than two of the aliens seen on screen at any one time. In the episode "Ordeal", Paul Foster is carried by two aliens while he is wearing an alien space suit, but one of those two aliens is always off-screen when Foster is on-screen.
