Chuffed that you'll be able to nail down Mr. Lovelock for this interview, best of luck!
As far as questions to be included, lots of great ones already mentioned (particularly interested in his take on the decline of Italian cinema and Manchester Morgue) but how about asking his opinion on La Settima Donna, his memories of the shoot, of Florinda Bolkan and playing such a reprehensible character in said film.
Also, Johnny-if you're looking for back cover text for the DVD, I'd be happy to lend my pen to your aid, sir! Just let me know either here or via PM. Cheers all!
