There is this thing about Shakespeare and high art. Much Ado is the play I've seen the most but Richard the Third is the belle of the ball. There is a schemer, a plotter. He is a villain.
“And therefore, — since I cannot prove a lover,
To entertain these fair well-spoken days, —
I am determined to prove a villain,
And hate the idle pleasures of these days.”
Note I've never seen Sir Olivier's version of Richard the III, as the Richard III in my imagination while reading the play is perhaps better than anyone else performance. On a side note, Johnny Rotten says that part of act in the Pistols, was taken form Oliviers Richard III.
