(p. 28) The calamity of Tubby the Tuba forced them to confront an unpleasant fact–namely, that they were in the wrong place for making good movies. Money was nor enough, they could now see. Technical genius was not enough (though Tubby had grave technical problems, too). Splendid equipment would not be enough.

Schure, although blessed with great foresight, could not be their Walt Disney.

(Note: my strong impression is that the pagination is the same for the 2008 hardback and the 2009 paperback editions, except for part of the epilogue, which is revised and expanded in the paperback. I believe the passage above has the same page number in both editions.)
