The book was, in Will’s words “a decade of work”, with a large number of people helping to write it, with a moderately large team promoting it (who did an awesome job!). There were a lot of adverts certainly around London for the book, and Will flew around the world to promote the book. I would certainly be hugely surprised if the budget was under $1 million (I know of projects run by undergraduates with budgets over a million!), and to be honest $10 million seems to me in the right ball park. Things just cost a lot of money, and you don’t promote a book for free!
Definitely not 2 orders of magnitude too much.
