Summer is the time of franchise sequels, of big comic-book movies, reboots, remakes, and regurgitations. Perhaps worse, casting news and Internet chatter now enable us to look into the foreseeable future, one in which it looks films with a number attached to the end will soon outnumber those telling stories we have not yet seen on the big screen.
There are more movies each year and hence the need for stories has never been greater. Technological advances have helped create special effects that would appear to make our imaginations the only limit to what could appear on screen. It’s probably the case that no novel is truly unfilmable, so Hollywood may get to these eventually. I’m just not holding my breath.
