We've discussed this in the individual threads, as all four have talked about this in interviews. I thought maybe it was time to put it all in one thread.
What we know is that it will be a two DVD set directed by Alex Gibney. This link is Wiki's for Alex: http://www.ask.com/wiki/Alex_Gibney. He's won an Academy Award for Taxi To The Dark Side, and has been nominated and short-listed for others.
Glenn has said many times that the first DVD will cover 1970 through 1980, and the second from 1994 to the present. If it's really 1970, then we'll get some 'pre-Eagles' background. I know I'm looking forward to the whole and especially this. So many books have been written about these guys and we've seen the errors in them which makes everything suspect as far as I'm concerned. So it'll be interesting to see what they put out there.
They have all said it'll be for Christmas or the end of the year. Yesterday, Glenn said he doesn't know how it'll play out, it'll be available for 2013, but it might go to theaters or TV first. Then come out on DVD. How cool would that be?
