Im pretty sure they just shot this in 2D, ran it through a computer to add 3D and then stuck an extra ?3 on your ticket for the privilege.
I don't know about that, but the trailer I saw for the next Pirates of the Caribbean definitely looked like faked 3d, and if it wasn't fake then they had had their lenses three or four times further apart than they should have. People had no depth, they just looked like cutouts, and there was "lol look at how far this sticks out of the screen hurr durr" crap.
I disagree about your general sentiment on 3d though, but my preferred theatre only plays 3D on their largest screens, which are pretty big. I just don't like how the glasses darken the picture and the 3D projector isn't bright enough to make up for it. Sure, 3D doesn't add anything significant, but I don't think it detracts either. If I actually have a choice I'm not sure between 2D and 3D for this though.
Whoa! you have to return your glasses? Ours come in sealed plastic things, then thrown out after the movie.
Adds an extra $1 on the ticket price for a pair
Yeah thats RealD
Here they used to do exactly that, then I think they started asking you to pop them in the designated bins on the way out to stop littering and mess (which is fair enough) and do some recycling (again fair enough, no point in waste for wastes sake). RealD use circular polarising lenses made of plastic. These are dirt cheap to make hence why it doesnt cost much to add them on to a ticket and hence why you can keep them or bin them after. The cost of their 3D system is wrapped up in the projectors and the new silver screen required for polarised projections.
Dolby use the 2 colour approach and their tech (in basic terms) adds a second color wheel to the projector set up. This means they can show stereoscopic images with slightly different colour tinges for each eye. You dont need a new cinema screen either but then the glasses are more expensive as a result because they seem to have some expensive coatings on them to try filter the images nicely.
This is one of Marvel's finest!
