According to RobertMcCammon.com, acclaimed Director Frank Darabont is still working very hard to get his adaptation of McCammon's popular book "Mine" off the ground. In a letter to McCammon, Darabon't states his intentions, but also mentions that his adaptation of Stephen King's "The Mist" will most likely come first.
Here is a snippet from Darabont's update to McCammon:
I came close to getting MINE into production this year, but it was a near-miss. For those who may not know, getting a movie greenlit for production is like having the planets align---countless factors all have to come together at the right moment for anything to happen. I remain committed to making MINE, and am currently in a search for the actresses to play the lead roles of Laura and Mary. I'm hoping to get the movie before the cameras at some point in 2006, although it might be later that year rather than earlier. That's because circumstance and opportunity (the planets aligning) might dictate that I direct my adaptation of Stephen King's great horror novella, The Mist, first. If so, I will likely start shooting The Mist this coming December, '05.
