Concept artist Scott Patton has released a CG model that he created in 2008 for the BioShock movie that was supposed to be directed by Gore Verbinski. The movie eventually fell apart due to budget issues. The studio didn't want to spend $200 million on an R-rated video game adaptation. At this point it doesn't seem like the movie will ever happen.
The studio wanted Gore to make the film for only $80 million, and he said no. He stayed on as a producer while the studio brought in director Juan Carlos Fresnadillo (28 Weeks Later) to take it on. Apparently BioShock creator Ken Levine stepped in and put a stop to the production. Word is he felt that Fresnadillo was not a good fit for the film.
