It seems that The Dark Tower films might get resurrected after being assumed dead. The initial plan was three films paid for and released through Universal Pictures while two limited TV series would run on NBC or a sister network. However parent company Comcast balked at the proposed budget. A lower cost script and plan was attempted but that was also rejected by Comcast executives.
Since then producer Brian Grazer said HBO expressed interested in the TV show aspect of the plan but nothing seemed to being on the movie front. According to Deadline this has no changed as Warner Bros seem to be close to signing a deal to have Ron Howard direct the first film with Akiva Goldsman making a script polish to meet WB's, not Universal's, notes for the film. This would then give the TV series side to HBO.
