So I was digging around the NPR archives tonight when I stumbled upon this little golden nugget. It was so far back in their archive it was only available in realplayer format. *shudder* So I went ahead and converted it for your aural pleasure: NPR's Morning Edition interview with Richard Marquand (May 25th 1983)
And if that wasn't enough Marquand for you feel free to read this interview from the June 1983 issue of Starlog.
