Thanks for asking! Well, honestly, you can get the DVDs for free if you are an interviewee for the film! 😉
Most DVDs are appr. $25. I am not trying to be evasive, but I’ve not yet finalized the way in which interviews will be mastered.
E.g., some recent interviews are 32 minutes, others were 90 minutes! So I may end up combining 2 or 3 per DVD.
