"The Pledge" movie poster- what are the techniques involved?

I'm trying to figure out how this is done, specifically- 1) how are the photos seamlessly blended into the paper texture background, and 2) how are the edges of the taped paper showing through without the photo blending into it?

very easy. the photo of the guy's face has a blend mode of overlay or hard light over the photo of the paper sheets peaced toghether. think layers man.

1) yeah...layermodes. Some pics may have been destaturated before the layermode change......and/or have had adjustment layers (or color overalys) added. Also im pretty sure the contrast and lighting was tweaked a bit on each pic.

2) the edges dont quite look like the photo's were blended over them though. It looks like the pieces of paper were used as a background......then copied with high contrast (so only the edges become visible) then using colordodge to blend back into the photo's. Also looks like a little blur tool here too.

Edit: Looking closer...the edges may have been inverted (so they're black) then selectively edited to give the 3d look to the edges. Even if im completely wrong here....you could try these techniques anyway . There is no right/wrong way to do anything in photoshop lol

was the paper made with clouds/noise?
or was it a picture
