It is ambiguous. “Hannibal Lector, how great an actor was he?” This could mean Trump thinks the actor is called Hannibal Lector, or the “he” could refer to the guy playing Hannibal Lector, which would be Anthony Hopkins. Like a lot of stuff that comes out of Trump’s mouth, it is an inarticulate mush, with the true meaning implied rather than explicit, and not worth arguing about.

So you have the quote where he says movie, character, actor and you still either lack the comprehension for it or you feel the need to argue maliciously in order to find something wrong with Trump

Do better, there are lots of things he does wrong
