The other day I was thinking of a movie I saw when I was very young, probably as a Sunday afternoon movie that my dad was watching or something. It was about a scientist who wants to terraform Mars and make the atmosphere livable for humans (I think it was Mars, anyway...). Now my brain is going to be unhappy until I find out what it was.
My memory on this is very hazy, but I remember at the end (SPOILER ALERT!!!) when the terraforming happens and everyone at NASA or wherever is celebrating. Then they see video taken from a probe that shows a bunch of creatures that look like dinosaurs lying dead on the Mars surface. Their atmosphere is now deadly to them, and they die instantly. All the scientists are devastated that they have done this.
That's all I've got. I think this movie was from the 70s or maybe early 80s. Could have been a made-for-TV movie, or even an episode of a show like Outer Limits. I think it was a movie though.
I tried IMDB with no luck and even ran down a Wikipedia list of "Terraforming in Popular Culture", with no luck.
And no, it's not The Wrath of Khan, or any other Star Trek movie. And not Total Recall either.
Any help would be greatly appreciated.
