I have scholarly proof: in his new book on DC, Jeff Thompson clearly states it was Curtis' idea, owing to Curtis' career background in syndication sales before he became a producer. He foresaw the viability of DS in possible future syndication- a market he knew all about.
Well, there's no citation for that one sentence about saving the episodes, and the author states in the book's preface that some of his information came from his fellow DS fans.
He also claims, in the intro, that ShadowGram scooped
Variety with news of the Depp/DS project by a day (p. 10), and yes, ShadowGram's email update arrived in fans' mailboxes hours before they could get their hands on a print edition, but comparing electronic info to news in print is like apples and oranges, and the fact is that
Variety had the information on the wires and the announcement was already appearing on the internet on the evening before ShadowGram sent it out.
