"24-page "Commemorative booklet" (including an essay by Hamilton Hamish and the original theatrical press book)"
The essay is not by Hamilton Hamish, it is by Steve Rogers. The essay begins with a quotation from James Mason's autobiography "Before I Forget" which was published by Hamish Hamilton.
This mistake is in the review http://www.dvdcompare.net/review.php?rid=242 as well.
