I have vague memories of a movie I watched maybe 15-20 years ago. If anyone can take the few details I am providing below and name the movie, I shall promptly download a bootleg copy. 
- Post-apocalyptic theme (chased by robots?/cybernetic nasties?/post-nuclear world?)
- Character’s name is Sinclair
- flashback scenes in black and white.
Not much to do an IMDB search; do you remember something similar?
OK, I shall buy the movie legally, if that makes you more willing to help.
Thanks!
