From what I gather, the Kazuis ( Fran and Kaz the couple that produced and directed the original movie) have pretty much seen their residuals from the series DVD sales bottom out. So, to get that money train moving again they are pulling out this reimagining of the movie.

Like most Whedonites, I have low expectations for this. I'll probably see it, more to see if it sucks more or less than the original movie.
