Jesus I had no idea there were that many adaptations in the works.
A Perfect Marriage seems like it'l be really good. I just have a feeling, they have a good cast. I don't know a whole lot about the director but I have high hopes for it. Would also be nice to see Scott Derickson take a crack at the Breathing Method. He's a good director, The Exorcism of Emily Rose was great but he often gets stuck behind the 8ball making films with stupid scripts (The Day the Earth Stood Still remake, Hellraiser Inferno) or even good ideas with not enough budget to make them right (Sinister was made for less then 2 million I heard, still came out decent). His new one Deliver Us From Evil looks pretty good.
The one I'm most looking forward to is Geralds Game because the guy directing, Mike Flannagan, directed one of my favorite horror flicks of the last few years, Absentia, which is a great Psychological horror flick. He also did Oculus, which ma have had a dumb concept (Haunted Mirror) but was still made rather enjoyable with the seemless back and forth between Flashbacks and the present. They couldn't have picked a better director for this story, he's about the only one out there I can see pulling it off.
