Richard Matheson’s 1954 vampire horror novel “I Am Legend” helped influence the zombie genre (it was the inspiration for the ‘68 George Romero film “Night of the Living Dead”) and popularized the concept of a worldwide apocalypse due to disease.

Join us – Pete Wright and Andy Nelson – as we kick off our disease series with the second of these adaptations, Boris Sagal’s 1971 film, “The Omega Man.”
