Harrison's a nice guy and lives in a wonderful estate right on Malibu next to Matthew McCanaughey's property. He was a real peach all through the interview and gave way more answer than he needed to... which is good!
We very lightly touched on his ninja movies withe Godfrey Ho. Just like I'd suspected he'd met Ho (who then was merely an AD) earlier on the set of the two Shaw Brothers epics he filmed in the late 70's, and acted in his ninja movies in the 80's as a favor. Ho was very courteous to him and a pleasure to work with, but then stabbed him in the back as soon as he left Hong Kong and re-cut his footage into at least 10 more movies!
While his crime films were not exactly my "favorites" of the genre, Harrison DID get to work with all the big Eurocrime directors earlier in the 60's... so he had some good stories about Lenzi, Margheriti, Castellari, and Marino Girolami.
The most hilarious story was about Umberto Lenzi while they were filming a spy movie "Mountain of Light" in Singapore. Apparently, Harrison thought it would be funny to hook Lenzi up with a transexual to shut Lenzi up (Lenzi was always angry and yelling on set). Lenzi ended up seeing the transexual for several days and thanking Harrison repeatedly for the introduction. Then, on the plane ride home, Harrison informed Lenzi that the "woman" he'd been "seeing" was a transexual. Lenzi got super-pissed for about 1 minute... but then cooled down and said "eh, it's all in the past!". And that was that.
