It's going to get redone by the original director John Carl Buechler. As far as I have read there hasn't been any script revisions, matter of fact he wants the original cast along with the original special effects artists; the artists have actually done quite well after Troll, bringing in awards and what not nowadays. The only downside is that Buechler wants to make it more of a family film. Hope it turns out to be as good as he's hoping it to be.
