Didn't see Colossus: The Forbin Project mentioned above. Unfortunately it is only out in Pan & Scan on DVD so I refuse to buy it.

I'll second nemein's suggestions of The Last Starfighter (one of my favorite "B" movies), Outland, and The Andromeda Strain.

See those two if you haven't already.

Westworld
Futureworld
Saturn 3
Damnnation Alley


And, since you listed The Ice Pirates and Spacehunter: Adventures in the Forbidden Zone, I would also recommend:

Metalstorm: The Destruction of Jared Syn
Yor: The Hunter From the Future
Space Raiders
Laserblast
Megaforce
Timerider
Battle Beyond the Stars
Buck Rodgers in the 25th Century

One of my favorites that seems to have slipped under the radar a bit is The Puppet Masters, from 1994. Donald Sutherland is the head of a secret US intelligence agency battling an alien invasion---an "Invasion of the Body Snatchers" premise. Great cast and action, tense atmosphere and very tight pacing, IMO.

If you like anime, I recommend Ghost in the Shell and Cowboy Bebop. Very interesting stories.

Plan 9 from Outer Space
Robot Monster (so bad it is good)
Species

Thanks for the tips, guys. I think I'm going to check out Outland and Battle Beyond the Stars next.

Don't know how good it is but George Pal's "The Power" (1968) is on TCM tonight. It is not yet available on DVD.

Amen. Science Fiction in its truest form.

So...have ya seen any suggestions yet "Joe?"

I'd say run, don't walk, to check out a copy of Gattaca.

wow lots of great recommendations, and I strongly agree with about 98% of them. big to the person recommending Puppet Masters, I own this one, and it's a great B sci-fi movie.

I should have added The Hidden(1987).

Good underrated sci-fi flick. Roger Ebert said it was a "Cross between Invasion of the Body Snatchers and The Terminator". I would loved to buy this DVD but Amazon.com listed this movie as Full-Screen when the OAR is 1.85:1.

I just watched The Andromeda Strain. Wow, I was entralled with this movie from the very beginning. Very cool opening. The environment of "Wildfire" with all the clean rooms and robotic arms and such was so cool.

Logan's Run is another very intriguing film.

taa455 -- is that the original or re- make of Andromeda Strain ?

The original 1971 version.

Well, unfortunately most of the really good suggestions (like Gattaca) I've actually already seen, but I just forgot about them while making my list. I knew I left a lot of stuff out. I was going to rent "Outland", but I couldn't find it at any of the local rental places, so I decided to just buy a cheap used copy online, but so far it hasn't got here yet.

A few people mentioned "Andromeda Strain" though, that's a movie I haven't seen but I probably need to. I'm putting that one next on my list. For now, I've got "Metropolis" rented and I'm probably going to watch that tonight. It's the 1984 rock version, so we'll see how that turns out.

Dom 56 you are on the money, add in The Crawling Eye and the H - Man

There was a remake?

There appears to be a Mini-Series that may be in production.
