Well... they have finally landed!
The North American release is here and my season 1, 5 disc DVD set arrived last week.
Paramount has added some extra features not seen in the European release, namely the extended 60 min. version of the pilot "Beachhead" and episode intros by Roy Thinnes.
The interview with Mr. Thinnes sheds some light on the making of the tv series as well, even if they let him ramble on a bit at times, it's still worth listening to him reminisce about his experiences with veteran actors, writers and producers, etc.
I've watched about three episodes so far and I must say the image quality and sound are quite good, considering at the time of the original broadcast I had only viewed it on a 20" black & white set back in the day, and this is the first time I've seen it in colour.
In fact it's funny listening to the narrator announce each episode... "The Invaders... in color", but don't forget, this was 1967.
The DVD set is very spartan/bare bones with no scene selection for each episode, but hey... the price was right.
More of a series dealing heavily with paranoia (the Red Scare at the time) with a sci-fi sub plot, The Invaders
didn't rely on very many special effects, just intelligent writing and good acting which IMO, makes it still watchable some 40 years later.
