Robert Walter Quarry (November 3, 1925 – February 20, 2009) was an American actor, known for several prominent horror film roles.

[1] During World War II in November 1943, Quarry joined the United States Army, where he formed a theatrical troupe.

[2][3][4] American International Pictures had plans for Quarry to succeed Price, signing him to a long-term contract,[5] but a variety of factors affected his career at the studio: the departure of AIP co-founder James H. Nicholson and business manager Paul Zimmerman, the decline in the company's fortunes that forced cheaper productions, and the subsequent degradation of popularity in old-style horror films.

[6] Quarry did make further horror film appearances, as the hippy guru vampire Khorda in 1973's The Deathmaster, and as a gangster in the 1974 zombie movie Sugar Hill.

[1] Quarry died on February 20, 2009, at the Motion Picture & Television Country House and Hospital in Woodland Hills, California, aged 83.
