I know it's an old idea that Mr. Roque embodies Ray in some manner. But watching that scene today, I was struck with the idea that Mr. Roque could symbolize Ray's conscience. (And by extension, the "conscience" of the movie industry in general.)
It's severely atrophied. Roque can barely move, and looks like someone literally shriveling up (with his head appearing too small for his body, thanks to "Little Mike" and the oversized body prop).
It's in a position of apparent prominence, given a commanding "office" on the deep within (or atop) Ray's building/psyche, complete with a servant ready to do whatever it demands. But at this point, Roque literally sits motionless in the dark until Ray comes in to consult him, and the servant seems almost coated with a layer of dust due to inactivity.
A functional conscience would be Ray's last bastion of backbone, giving him his marching orders and helping him make the right decisions in difficult situations. Instead, he has Mr. Roque... who barely responds at all ("Yes?" "Then?"), rather than encouraging him to do the right thing.
Out of the tension between the tantrum-throwing Id and the demanding Superego, the healthy Ego is supposed to arise. But Ray's (Hollywood's?) Superego produces no such tension, issues no demands, and certainly makes no attempt to "physically" force the petulant Id back on the right track (within this symbolic landscape). How could it? Roque is not only unable to move, he's completely disconnected from Ray by the transparent barrier.
Ray (and Hollywood) has a crippled conscience... one that scarcely advises even when consulted, and that meekly abandons artistic vision and quickly acquiesces when the money players pout...
