Roadshow format basically means including an intermission, and in this case also an overture, entr’acte, and full animated opening titles — in the style of the widescreen epics of the ’50s and ’60s.
The main purpose of the edit is to make a coherent single film out of the material; I’m using “Roadshow Edition” because it’s the most obvious distinguishing feature, and I didn’t want to just use my name.
