The LA Times ran an interesting article on stereoscopic 3D movies:
About 52% of ticket sales from “Clash of the Titans” were from 3D ticket sales despite the fact that 3D tickets generally charge a premium over 2D tickets.
Clash of the Titans pulled in a box office draw of $61.4 million. Market Analysts estimate that if the film were only released in 2D, it’s draw would have only been $41.4 million.
The 3D effects in Clash were actually low quality, because the film was originally made to be 2D and the 3D effects were retrofitted after the fact. Many fans of 3D technology are predicatably insulted by this.
One studio chief, commented anonymously to the LA Times:
“You can make so much more money with 3-D that it essentially puts a tax on 2-D dramas, romantic comedies and other projects, since they just won’t project the same kind of box-office potential.”
