Anna Paquin and Stephen Moyer are keeping it all in the family with their new project, Open House. True Blood‘s engaged duo co-star in this thriller about an upscale couple in Los Angeles who host an open house to sell their luxurious mansion, only to discover later that one of the potential homebuyers never left.

Open House is written and directed by Andrew Paquin, Anna’s brother, and co-stars Tricia Helfer, Rachel Blanchard, and Larry Sullivan. Filming took place in Los Angeles this summer and the film is currently in post-production. Look for it on the big screen in 2010.
