How to make this 3D photo wall effect in Photoshop?

How can I create a photo wall effect similar to this with Photoshop CS6?

I tried with Warp, but it looks so bad and it's nowhere near comparsion. I also tried with Edit->Transform->Perspective, but then it looked more like this and not what I wanted.

I'm also trying it on a smaller image (800x415) and I have lots of thumbnails similar to the ones in the original hulu image, but I merged them into one big image with the idea that it'll be easier.
