My author chum Paul Talbot (BRONSON'S LOOSE!) has penned another book, and it's just now become available:
http://www.amazon.com/Mondo-Mandingo-Falconhurst-Books-Films/dp/1440175969/ref=sr_1_1?ie=UTF8&s=books&qid=1256742607&sr=8-1It primarily covers the movies MANDINGO and DRUM and the associated novels (and Broadway play!). But of interest to euro-cult fans is the fact that the book also covers "other 'slavesploitation' and 'spaghetti Mandingo' movies."
A while ago, I sent Mr. Talbot an interview with Ken Norton from an old '70s issue of FIGHTING STARS magazine, so he's kindly sending me a comp copy. I'll give a full report when I get it.
