HOLLYWOOD THEATERS SOUTHGLENN STADIUM 14 Centennial, Colorado USA
A shot of one of the large auditoriums looking from the balcony. Could that be side masking? In a new theater? Excellent! Hollywood Theaters deserves a commendation for this. Or, at the very least, it has a combination of side and top masking (it looks like the sides are in and the top is down). This particular auditorium has yet to ever play a movie at the time of this picture.
