Started with building a room in After Effects. I wanted to give the feeling the wrestling was in this enviroment getting ready to face his opponent on the mat. I wanted it to look weathered but have a little old-school locker room type-feel. Spray paint, concrete, and photos on the wall

Close up of one of the walls. Added a few buzz words like "100 Years" and "Tradition."

Added a flare and some grain to the room

Then added the keyed out green screen clip. Added a few color treatments to the subject in order to bring him out and make him pop a bit more
