This short video recently appeared on YouTube, announcing that the trailer for Ender’s Game will be released in less than a week on May 7th.  The video then gives just a few shots of some special effects, characters saying their lines, and battle school students standing there looking at something.  The special effects look good, but it’s too early to judge much else.  Obviously the film will not be like the book, so book fans (myself included) should get that out of their heads right away.  A lot of the book’s power depends on being able to see inside Ender’s head over the course of years.  There’s obviously no way to film that sort of thing, so the power of the film (if it will have any) will have to come from somewhere else.
