HOLLYWOOD —  “Cabin Fever” director Eli Roth came to his debut film’s preem in full horror makeup Friday night, although not everyone at the Egyptian Theater or Star Shoes after-party recognized his homage to Japanese villain Ichi the killer.

The irrepressibly enthusiastic Roth, who had his parents don both paper bags and surgical masks during the evening, thanked Martin Brest for kick-starting his ambition by firing him as a stand-in on “Meet Joe Black.”

Lions Gate acquisitions prexy Peter Block, a horror buff, said he had been tracking the pic even before its Toronto screening last year and appreciated that it wasn’t a slick Hollywood production. Also toasting Roth’s gory debut were horror vets Tobe Hooper and David Hess, Nick Stahl, “Cabin Fever” producer Lauren Moews and thesps Cerina Vincent, Jordan Ladd, James DeBello and Joey Kern.
