I don't know how many of you have seen this film. Interesting concepts. See it's called The 6th Day, and stars Arnold Schwartzenagger. In it all clones are marked with a dot on the inside of their left lower eyelid, one dot for each time they've been cloned.
Ok 2 screen caps that I did from The 6th Day

the only alteration was the arrow to indicate that mark as it's kinda hard to see... I've had that spot since I was like 3 or 4. Pretty freaky; art imitating life. Freaked me out when I first saw the movie. Though I must say, I seriously doubt they had anywhere near this tech level in the 1970's.
