"...Nor are there any extras on the DVD, surprising with something that's considered a TV landmark. That's even more surprising when you see that CBS is releasing a short-lived TV series on DVD on Tuesday, with extras.
That set is The Invaders: The First Season (CBS, 17 episodes, five discs, $36.98), the 1967-68 series about a man, David Vincent, trying to stop an alien invasion of Earth after he stumbles upon the landing of a flying saucer.
The series came from the same producer as The Fugitive, which was nearing the end of its network run as The Invaders went on the air; both have the same elements of a man on the move with a story no one will believe, lots of guest stars, a somber narration and a strong current of paranoia. But The Invaders was not a big hit, and it had some very silly moments — such as the extended pinkie finger that distinguished aliens taking human form.
But star Roy Thinnes was a sturdy actor and, aside from special effects that were unremarkable then and now, the show has some effective moments. And it's a time capsule of television, especially in the opening boasting the show is ''in color.''
DVD extras include three promotional spots from the show's run, an extended version of the series premiere, about half an hour of Thinnes talking about the show (and his own views about UFOs) and introductions for each episode by Thinnes....."
