Disney intends to continue to release 3-D versions of its biggest animated hits, including a few of Pixar’s. Last year’s “The Lion King 3D” kicked things off. The downside of this development involves some legitimate grousing about the general spottiness of 3-D conversions and how no one truly yearns to see Mufasa raising up Simba right on the bridge of your nose. But the re-released movie was a hit. Conversions of “Beauty and the Beast” and “Finding Nemo” followed; brace yourselves for “The Little Mermaid,” coming next September.

These movies were all popular before 3-D became a permanent fixture of certain types of moviegoing. It’s easy and perhaps healthy to fret about the profit motive and Disney’s genius for making it impossible for a parent to avoid spending money on the same movie simply by changing the movie’s format.
