Can't get enough of Southern belle Sookie and hottie vampire Bill Compton? Well, the duo – the actors playing them anyway – have signed on to star in a movie together.

Unfortunately it's not a film version of their hit TV show True Blood, but instead the real-life couple will star in a thriller, Open House slated for a 2010 release.

IMDB.com is reporting that the pair, who are engaged to be married, will play a couple who discovers that days after an open house a potential buyer of their home never left. The movie is written and will be directed by Paquin's brother Andrew who recently produced the Renee Zellweger romantic comedy New In Town.
