Incredibly Strange Films. The very first time I ever heard the man speak was on the British TV program "The Incredibly Strange Film Show," which was syndicated in the U.S. on the Discovery Channel cable network. The series served as a fantastic primer for the films of everyone from Fred Olen Ray and Ray Dennis Steckler, to Sam Raimi and Tsui Hark. The Lewis episode briefly covers his entire career (up to that point), and even includes a tour of Miami's Suez Motel, conducted by Blood Feast star William Kerwin.
I've included a clip from that episode below, but you can find the entire episode (in four parts) here.
