Although it's still not confirmed it was mentioned that Jonathan Liebesman is in final negotiations to direct the movie. I watched the Texas Chainsaw Massacre: The Beginning and Battle LA, and although they didn't get very good reviews I enjoyed them and I think that this man has a certain visual style (especially after seeing the Wrath of the Titans trailers and featurettes). I think Platinum Dunes made a great move hiring him. I believe that he will fit in perfectly.
Also we have to bear in mind that Wrath of the Titans budget is very close to $100 million (as is the TMNT one). And he really made a very good looking heavy on CG film (at least from the trailers). Just have a look at this featurette where you can see the director himself if you still don't know him.
We have to wait and see in December 2013.
What do you think about him?
