Buried on this page about Sci-fi Channel news is the following:
RINGWORLD: Based on Larry Niven’s RINGWORLD series of novels, a four-hour mini-series is in development. In the future four explorers crash on an artificial structure in deep space, a mammoth ring that circles a distant star. Exploring this strange place, the humans discover that there is life here and secrets that could change the universe forever.
I’d be terrified that it would suck but I thought their Dune mini-series was OK and the Battlestar Galactica remake was quite good, so here’s hoping.
