You can draw lines between 2001 and TMP. Thematically and broadly, both movies wonder if the next big step in evolution isn't some state of existence beyond the linear, finite, rational, physical. Heady stuff. It's a huge theme in 2001.
Sure there's that common theme, but to me
TMP and
2001 are about as different from each other as (in the realm of time-travel stories)
Back to the Future and
Time After Time; one is not reminiscent of the other.
2001 is all about mystery - in fact the last words of dialogue are "its origin and purpose: still a total mystery" (the taped message to the crew that plays just after Dave deactivates HAL, concerning the lunar monolith). The audience is left to make up its own mind about what happens to Dave, and to Earth for that matter, in the final "Jupiter and Beyond the Infinite" section that immediately follows.
TMP, by contrast, has the bridge crew saying things like "we've witnessed a birth" (well, duh) of a new life form that is now (conveniently) off in some other dimension. Oh, and by the way, they've saved Earth from destruction (unfortunately something that happens way too often in future Trek movies). Spock's back, everything's cool, "Thataway," and finally a slogan about the human adventure that we've already seen on the damn posters outside the theater. Nice and neat.
TMP and
2001 are also very different with respect to music. The two movies might have been more similar if Alex North's original score hadn't been rejected by Kubrick in favor of the R. Strauss, J. Strauss, Khachaturian, and Ligeti recordings he'd been using in assembling rough cuts. This choice to use exclusively preexisting music was radical; I can't think of another example this early (not counting
Fantasia). Even
The Graduate, with its predominance of Simon & Garfunkel songs, also included original music by Dave Grusin in at least three important scenes.
