Weeellll, it is Hallowe'en. This is A girl is possessed by a demonic entity that resists all efforts to free her from its grasp. Only one priest has the inner strength to tackle it - but he too is soon left reeling by the powers of darkness. William Friedkin's extended cut of the horror - starring Linda Blair, Ellen Burstyn, Max von Sydow, Lee J Cobb and Jason Miller - features some really nifty upside down crab walking walking for 1973. Some of you may find the effects hilarious, but it's a damn sight better than this evening's horror alternatives... RTE2 are showing the sequel to 28 Day Later, that being 28 Weeks Later, at 9.00pm. And they're following this with, wait for it, Halloween 6: The Curse of Michael Myers at 11.15pm. From 1995. The niece of masked killer Michael Myers saves her baby from being a human sacrifice and leaves the infant in the care of a man who as a boy survived an encounter with the maniac. The Exorcist it is, so.
