I doubt it is him, and dont understand why we all of us as a collective cant just forget about it until the end of the movie.  Why do you have a problem with people taking guesses and trying to figure it out?  Think of it like this; Do you worry who the main camera person’s name the whole time the movie you want to see is playing?  Equating this to some Jewlywood horseshit is really quite stupid, IMO.  We're SUPPOSED to be digging.  Let it go.  Telling (probably) adults on the internet what to do.  Classy.
