If you ever read or look at Scarlet Street magazine, they had a "lengthy" interview with him about 10 issues ago, as well as a very good exegesis of the Fright Night film itself. Scarlet Street also has an ultra-cool website:
www.scarletstreet.com -- see especially the ongoing analysis of film-noir & overlooked genre films. Best B-actor interviews anywhere.
Some folks get put off by the sometimes gay-themed slant to some of their articles, but if you find that repugnant just skip through & get to stuff that interests you. It's worth the digging.
