I'd like to point out that eliminating this trope page would be a grave mistake.
This is a trope that has been around since at least 1938: Witness this clip
It has also commented on in various media, quite far from just movie critics. So it is a well known trope with the general public: http://shoemoneytonight.tumblr.com/post/9252827994/via-dinosaur-comics-t-rex-knows-whats-up
As for the name. I suppose we could rename it, though the only thing I can think of that could be clearer is to add "Scene" on the end. However, I do think this is the pre-existing name for it. Do we have any film students or professionals out there reading the thread? Is this a standard term for this kind of thing or not?
