I just read this over at Sci-Fi storm, it sounds like there might be the possibility of a B5 movie again:
QuoteCould a big-screen, big-budget Babylon 5 feature be in the works? Well, not yet, but according to JMS Warner Bros is warming up to the idea (http://sknr.net/2009/01/19/warner-bros-may-be-ready-to-bring-babylon-5-to-the-big-screen/) - now that JMS is a big screen writer. The first item for discussion from WB is apparently, "...how big a movie would it have to be for you to come back and make a B5 movie for us??

I was a big time B5 fan before it got messy in the last season (and the failed miniseries) but I'd love to see it back, especially on the big screen!
