Mark Calaway doesn't really do a lot of interviews, something hinted on during a previous entry. The man seems to prefer letting his character do the talking for him, rather than appearing on podcasts routinely or giving much away during sit-down interviews. Interestingly however, The Undertaker will appear on Steve Austin's show on the WWE Network soon, which should be one of the most gripping chats ever between the legendary pair. This represents a shift in how Undertaker is perceived in WWE. Now - more than ever - an elder statesman for the company, Mark Calaway could slot nicely into the role of ambassador for the promotion, in a similar fashion to what the likes of Hulk Hogan and Austin himself do. It seems likely that 'Undertaker: 25 Years Of Destruction' will feature a bevvy of interview material with the man, because that would be a major selling point for the entire project. Fans haven't really had a whole lot of The Undertaker discussing his character over the years, so this book - along with the proposed DVD and the Austin interview - could be the time to change that, and there's money to be made from his thoughts.
