Some elements are in the video and others generated by the game itself. I only ever played it in Las Vegas back in the 80’s. I could have sworn the one I played had Clint’s actual voice throughout.
I feel like watching that too long could give me a seizure! I guess the way the disc is formatted helped avoid the blank screen issue other LD games had sometimes when accessing the next required video sequence.
Too bad the Battlestar Galactica LD game they were working on never made it past a prototype.
