The Speaking Ring

From ComicBookMovie.com:

Conceptual illustrator, Gregory Hill ("The Amazing Spider-Man 2"), has updated his website with concept art that he created for Universal's cancelled film adaptation of Stephen King's The Dark Tower, which Ron Howard ("Rush") was set to direct.

Over the years there have been several attempts to adapt Stephen King's epic Dark Tower series for the big and small screen. The closest attempt, and the most ambitious attempt, was Ron Howard's adaptation, with Universal set to produce. Howard planned to make three movies, but there also be a television mini-series in between each film. The financial risk became too much for Universal to bare, so they passed. Howard then took it to Warner Bros. but they too passed due to financial concerns. Last year, Howard said he is still hoping to move forward with the project but would keep mum until there was more concrete news to report. The screenplay was written by Akiva Goldsman ("A Beautiful Mind") and it would've been produced by Brian Grazer, Goldsman and Stephen King.
