Two generations of exploitation filmmakers dish up their versions of scary at the Plaza Theatre this Halloween. On Sat., OCT. 27, the Silver Scream Spook Show gang presents D-movie kingpin Ed Wood's creaky classic PLAN 9 FROM OUTER SPACE (1959; pictured), featuring a posthumous performance by Bela Lugosi in footage that Wood inserted into his sci-fi opus. On Halloween eve Tues., OCT. 30, gore hounds can enjoy the old-school answer to today's torture porn, Herschell Gordon Lewis' 1963 BLOOD FEAST, featuring a Playmate and oodles of blood, part of the Plaza's new monthly Splatter Cinema. Both movies repeat on Wed., OCT. 31. Sat., 1 p.m. show: free-$6, 10 p.m. show: $10; Tues., $8.50. 10 p.m.; Wed., $7.50-$13.
