How to remove object behind a moving subject?

Hello, I have tried everything to try to remove the black mask behind the moving subject. 

 

The shot seems static, but it is handheld so it is moving slightly. 

 

I need to complete this edit immediately, would really appreciate if someone could help. Thanks.

I duplicated the footage layer, added a freeze frame to the duplicate, drew a feathered mask over a clean part of the wall, Pre-composed moving all attributes, cropped the pre-comp (Composition/Crop to Region of Interest), then moved the clean part over the object on the wall and added corner pin to line up the perspective.  That fixed the wall.

 

Then I duplicated the footage again, set an outpoint to where the actor passed the thing on the wall (only six frames), added a feathered mask about in the middle, and drew a rotobezier mask to isolate the actor's head and shoulders. Moving back and forth in the timeline and moving the whole mask, I got a reasonable result with only four keyframes. 

 

You could also export a frame to Photoshop Layers and create your Clean Plate there instead of using the pre-compose and corner pin workflow. This is what that looks like:

Seems easy enough to just duplicate the layer, move it into position and then mask out the stuff to cover up the mask. Of course you have to do it by hand due to the foreground being out of focus. Otherwise this probably could just as easily be replaced completely with a photo or even something created entirely in AE from a bunch of solids with fractal Noise and grain textures.
