The talk show scene.
Usually, when actors appear as characters in talk shows, the host calls them by the character's name. In this scene, the host said "ROBERT ENGLUND". Acutally, I think it would've been more surprising for the audience and HEATHER if the host hadn't said anything. Imagine that: ROBERT as FREDDY clawing the set like he did with no warning. Isn't that the point?
This is a good example of what I'm saying (and keep in mind that these characters aren't meant to be scary): https://www.youtube.com/watch?v=Q0VGRlEJewA
