They should do a big budget Invaders movie
like other 60s tv show movies over the past years - Fugitive, Mission Impossible, JJ Star Trek etc
i know they did the mini series in 1995 but honestly who knows about that beyond hard core fans?? (and beyond the Roy Thinnes blink and you'll miss it cameo had very little in common with the original show)
and i know various big budget movies of old tv shows haven't worked (Lost in Space, The Avengers, A Team etc) but The Invaders would have a good chance as the concept is so strong (& the central theme of an outside force trying to take over from within is especially apt today) so Paramount or whoever owns it could do a biggish budget movie (but NOT another tv show). In addition although The Invaders was/is a highly respected tv show to SF fans it generally isn't all that well known in the popular culture now so it would've been deemed too sacrilegious if it were remade (unlike a lot of other stuff that gets remade)
as fun as it would be i dont think they could do a sequel to the original series to allow Thinnes to cameo as Vincent (like the mini series) as then the main character would have to be called something other than 'David Vincent' (youd really need to keep that name as its just synonymous with The Invaders) plus it wouldnt really work having the invaders been trying to take earth for 40 years (and of course youd want to recreate the iconic opening of the saucer landing at the deserted diner)...so itd work better if the concept of the original series was just updated for today - a remake like The Fugitive or A-Team or Star Trek...Thinnes could cameo as another character (a fellow believer?) or even an Invader (Vincent had an almost cold detached look about him like he could almost be an Invader himself - maybe that was intentional in a blade runneresque type way?*) ...Or maybe even have it as a period piece set in the 1960s, itd certainly set it apart from countless other alien invasion films and the 60s are in vogue now thanks to Mad Men and stuff like X Men First Class. plus more importantly it would solve any problems of the invaders being exposed by any of todays technology (smartphones, CCTV, Google earth etc) - they could either remake it from scratch set in the 60s or have it as a sequel carrying on from season 2 (minus The Believers though)
Either way have that same eerie/horror feel that the tv show had (and also the Sutherland/Nimoy Invasion of the Body Snatchers remake) - Vincent alone against the Invaders visiting small towns etc, people not believing him, getting evidence but then losing it, people he trusted being revealed to be aliens - plus dont deviate too much from stuff in the series, like the saucers, killer discs, incinerator guns, hypnotic twirling things, regeneration tubes, little fingers, blank stares, green suits, invaders disintegrating bodies when die, the eerie theme tune etc - all the stuff that the 95 miniseries chose to ignore
Could do a big budget version of the pilot episode - obviously not exactly the same - but similar set up to that - Vincent in his car - wrong turn, deserted diner, seeing the saucer land etc...then have a story that incorperates elements of various episodes, expanded for a big budget - e.g. smalltown investigations and death of his comrade (the pilot) maybe Vincent could capture a ship (The Saucer) or gets evidence (Quantity: Unknown) etc etc
throughout the film hed convince the odd person/scientist etc but theyd always die or choose not to accept what was happening - youd really want to keep that one man against the Invaders thing - not diverge into 'the believers' thing season 2 had (at least not until a sequel anyway)
End the film with a minor victory for Vincent -destroys an Invader complex or a saucer taking a few aliens down - but in doing so he loses any evidence he had so itd be bittersweet - and obviously the threat is still there at the end - his victory is just a drop in the ocean
if successful then do sequels which could expand to the believers, Invaders origins etc - but really itd be a standalone film - if theres sequels fine, if not then itd still work on its own. one of the cool things about the tv show is they never wrapped it up (obviously as it was cancelled!)
who for David Vincent? Would need someone who's an above the title star (like Ford in Fugitive/Cruise in MI etc) otherwise it probably wouldn't make money as The Invaders name alone wouldn't be enough to ensure success. Kevin Costner would’ve been a good choice in the 1990s (as he looked a little like Roy Thinnes) but abit too old now. Maybe Russel Crowe would be a good choice (as he has that lone guy against the world thing down..) or maybe Patrick Wilson (around correct age and whos abit 'Thinnes'). And who for lead Invader? (theres was always a lead Invader guy right? Or someone you think isnt but turns out he is) maybe someone like Kevin Spacey or Jeff Bridges as they have that detached serene spaced out persona (both 'StarMen') or even Chris Walken or Kiefer Sutherland (whose pops was in Invasion of the BS)... so maybe a couple of those guys
hopefully this decade we might see a big Invaders movie as they are running out of things to remake now (Twilight Zone and Outer Limits movies should be going ahead soon)...so maybe they'll be looking at the more obscure, less obvious stuff like Invaders
