My take on it is, the only way it would be too common is if ALL movies were 3D. Sort of like how "color TV" is too omnipresent to be a trope.
3D movies aren't that widespread yet. Further, the fact that a movie is released as 3D is often cited as a specific selling point, or as a failing point in the case of movies not intended for 3D that were converted after the fact.
ok, so as I understand it, there is no such thing as a self-explanatory trope. So if Three D Movie is placed on a work's page it would need an example besides "this movie is in 3D" which is also a no-no. What else could you say? Therefore, IMHO, what's the point of listing it?
Black is Order, White is Chaos.One way of looking at it is that in general an item is only tropable if it serves a story-telling purpose. In the present case, this means that a movie being in 3D is only interesting if the 3D adds something to how the story is being told or how the audience perceives the movie.
And in that case it should be possible to expand on the example and explain how the 3D is being used or how it is a part of the audience experience. For example, for Gravity you could write something about how the 3D enhances the initial spacewalk sequences.
If you truly can't think of anything to say about this, then leaving 3DMovie as a ZCE is pretty pointless. Instead it could perhaps be mentioned in the general description of the movie, rather than being listed as a trope?
Edited by GnomeTitanWould it not make more sense for Three D Movie to be a Trivia item rather than a main?
Edited by CrypticMirrorGravity's plot (its a fairly standard disaster movie in plot terms) would be unaffected if it wasn't made in 3D, it might not look as pretty, but the story would be unchanged. To me that makes it a shoe-in for Trivia, no different from Jaws 3 D's own gimmick.
^^Granted, the *plot* of Gravity is not affected by the 3D, but it does enhance the spacewalk scenes. So it's not a *plot* device, but it is a storytelling device. An analogy is Hitchcock's choice of doing Psycho in B/W because of the way the blood in the shower scene would look in colour (though the analogy isn't perfect because he removed a dimension from the medium rather than adding one). This makes it more than trivia IMO — the impact of the film would have been lessened if it hadn't been 3D.
Three D Movie is a production trope, and to a lesser extent a marketing trope. It's not a story trope, necessarily, although sometimes it can involve characters Breaking the Fourth Wall as a visual gag. These details are what make it interesting — more than just a dry mention that yes, this movie was filmed in 3D. That's the point of tropes — to find the interesting bits!
Edited by Fighteer "It's Occam's Shuriken! If the answer is elusive, never rule out ninjas!"So what should we do if we see a context-less Three D Movie? Delete it, comment it out, move it to trivia?
Black is Order, White is Chaos.

Is Three D Movie a trope to be placed on a work page? A lot of the time it just appears on the page with no context as "self-explanatory". With 3D becoming so widespread, isn't it now too common to be a trope?
