I know this brands me a heretic every time, but 2001 just isn't one of my favorite films. It has some great moments in it, but like a lot of Kubrick, I find it rather flawed. Go ahead, call me names. Everyone does.
There was not only the standard movie adaptation comic, but a series that followed as well.
Update: The scans have been taken down. If you Google Image search for "Jack Kirby 2001," however, you can find some still.
