Partial answer, a stretch at best, but hopefully pointing someone in the correct direction:
•Forgets Yon Attracts
Taking the second word, Yon, first. This is a very unusual choice, suggesting that the word we're looking for is well-know for being the opposite of Yon. The only thing that springs to mind is:
Hither, as in "Hither and Yon"
Now looking at Attracts, the opposite that seems most likely to me is:
Playing with the letters from these two words I was able to come up with:
This is only missing 2 letters to give the name of someone famous and, at a stretch, a possible opposite of separates is:
co- meaning together (e.g. co-conspirator)
This means that the third person on the list is:
Christopher Lee and the sequence might possibly be something to do with actors who have played bond villains or sith lords, however Christopher Lee's credits are incredibly long, so they could be almost anything.
Looking for other famous Christophers who have the letters EEL in their surname, the only one that jumped out at me was Christopher Eccleston, which would give "actors who have played The Doctor" as a good sequence to investigate, however I couldn't get the letters COCCSTON to make a word that means the opposite of forgets, separates or undoes. I Also couldn't get the other clues to match with Paul McGann and Sylvester McCoy or David Tennant and Matt Smith.
