This is one of my many "favorite movies of all time". It was made for TV, but the acting in it is so outstanding, and it covers in detail (and rather accurately, according to a few inside sources) one of my favorite points in history: the birth of the personal computer (namely, the big Bill Gates vs. Steve Jobs championship fight for money & power, hehe).
Bill Gates is played shockingly well by Anthony Michael Hall.
It's just over an hour and a half, so grab some popcorn, switch to full-screen, crank it up and enjoy:
