The horror is Legion.A woman crawls by unnoticed - on the ceiling lika a fly. A long-dead killer claims victim after victim. Flames erupt, snakes slither, the ground opens and reveals a writhing pit of the damned. The evil is back. Also back is the creative force whose novel and Oscar® -winning screenplay shaped the trailblazing 'The Exorcist'. Adapting his novel 'Legion', William Peter Blatty writes and directs 'The Exorcist III', a jolting foray into terror that begins where the first film ended. George C. Scott plays police Lt. Kinderman, investigating mysterious murders. Kinderman doesn't believe in demons and possession. Not yet. Jason Miller reprises his priestly role from the original. And look for Samuel L. Jackson, pro basketball's Patrick Ewing and more bit-role surprises.
