I thought you folks might find this of interest. It's not directly related to Nightstalker but it does concern one of it's main players. Gabrielle Union has a supporting role in a yet-to-be-released film called "Running with Scissors". In the film, she portrays the lesbian lover of Annette Bening's character. Here's an article where she discusses that part(as well as some other film roles she's had lately).
On IMDb, the release date is listed as September 22, 2006. (I find it interesting that Brad Pitt and Jennifer Aniston are listed as "producers". Perhaps they started this project before their big break-up. Who knows).
