Avoided this movie when it came out based on publicity which made it look like a Solaris clone - it is not. Also - it is not an action movie - expect lots of nothing-much-happening which is later essential in explaining events.
Truly classic golden age science fiction with links to Clarke, Asimov, and Phillip K Dick.
Trivia: The director/script writer is also the son of David Bowie. Somehow this seems appropriate.
