Super-short, not exactly original, but well-done and strangely foundational: The Egg is a wonderful little, tiny, short story. I first read it some years back, but it always stayed with me, just in the back of my head. Now I came across it

Gods, I already knew they had chosen Matt Damon as lead role, and I can imagine him in that role so very well! Brilliant humor with hard scifi. I seriously hope they won't fuck up the movie.
