Re: Best Actor
Then there's Screen Presence. Not all actors have this, some have it in spades. It can be hard to separate acting ability from this special charisma. Examples: Russell Crowe, Cate Blanchett, Glenn Close, Laurence Fishburne (these are just a sample - many of the actors already mentioned have "it" ). These ones can all act as well, though, as evidenced by the fact that they have the ability to turn their screen presence "off", and play someone very blah or background as well as someone you can't take your eyes off.
Not every great actor has Screen Presence. You don't actually need it to be a great actor. For example someone like Steve Buscemi or Toni Collette, who have played some excellent roles showing fabulous mastery. The "quiet achievers" of the acting world.
Do you need both to be called a truly great actor?
