It is a time of heroes, and the mighty warrior “Beowulf” slays the demon Grendel and incurs the wrath of its monstrous yet seductive mother, in a conflict that transforms a king into a legend. Groundbreaking director Robert Zemeckis offers a vision of the Beowulf saga that has never been told before. “Beowulf” stars Oscar winners Angelina Jolie as Grendel’s mother, Anthony Hopkins as the corrupt King Hrothgar, (note: both were also in the dreadful movie “Alexander”), and Ray Winstone as “Beowulf.” The film also stars John Malkovich, Brendan Gleeson, Dominic Keating, Alison Lohman and Robin Wright Penn. ( the graphic novel Sandman) and Roger Avary (“Pulp Fiction”) adapted the legend (whose writer is still anonymous, after nearly a millennium), for the silver screen.
