"2001" is a story of evolution. Sometime in the distant past, someone or something nudged evolution by placing a monolith on Earth (presumably elsewhere throughout the universe as well). Evolution then enabled humankind to reach the moon's surface, where yet another monolith is found, one that signals the monolith placers that humankind has evolved that far. Now a race begins between computers (HAL) and human (Bowman) to reach the monolith placers. The winner will achieve the next step in evolution, whatever that may be.

Stanley Kubrick worked for several months with effects technicians to come up with a convincing effect for the floating pen in the shuttle sequence. After trying many different techniques, without success, Kubrick decided to simply use a pen that was taped to a sheet of glass and suspended in front of the camera. In fact, the shuttle attendant can be seen to "pull" the pen off the glass when she takes hold of it.

Goofs
Incorrectly regarded as goofs:
When Bowman is carrying out the EVA to replace the AE-35 unit, Discovery's aerial is seen rotating. Normally the aerial is directed to Earth, and unless the ship itself was changing position the aerial would appear stationary. However, the device which controls the positioning mechanisms of the aerial is the AE-35 unit-the unit being replaced. During the time Bowman is exchanging the AE-35s the aerial would have no hardware control, and there is also a small but real possibility that the replacement AE-35 might be faulty. It is reasonable to assume that the aerial would first be rotated to its default position (facing forward, away from Earth) and mechanically locked down until the new AE-35 unit is installed and checked out. The rotation visible in the scene is consistent with that.

The traditional "roaring lion" logo for MGM was not used in this film.
Instead, the newly designed corporate logo for Metro-Goldwyn-Mayer was
used, along with the letters "MGM", all in white against a blue background.
