From NetFlix:

Directed by Robert Zemeckis, Beowulf tells of the great 6th-century Scandinavian warrior called upon to defeat a manlike ogre named Grendel (Crispin Glover), a descendant of the biblical murderer Cain. Based on the longest surviving Anglo-Saxon poem, this film adaptation’s notable cast includes Anthony Hopkins as King Hrothgar, Angelina Jolie as Grendel’s tormented mother, John Malkovich as Unferth and Ray Winstone as Beowulf.

There are at least two movie versions of the story. When the 2007 movie came out I decided to plough thru the actual Anglo-Saxon saga of Beowulf. Seamus Heaney produced a version that had Old English on the left side and his English translation on the right side. Frankly, I was a bit bored by the classic saga. It’s fairly straight-forward: man meets monster, man slays monster, man goes back home. So I can see why the movies spiced it up a bit.

I can only recommend this version to horny male teenagers eager to
see Angelina Jolie arise out of the water for all intents and purposes
naked.

Having said that, this is supposed to be a 3D movie although I am not
sure where I have to go to see it in 3D. I would be willing to re-see the
movie in 3D just to see how successful it is. The novelty in this movie
is that all the characters are real people whose appearances have
been digitally altered. I did not recognize Anthony Hopkins’ face, but
his voice was unmistakable. I recognized Jon Malkovitch’s altered face.
There are so many special effects (wow – what a dragon !) that 3D
might be fun. According to IMDB, Ray Winestone (Beowulf) is the voice
of Beowulf in some kind of video game based on Beowulf.

Having said all this, if you want to see a Beowulf film, please see
instead “Beowulf and Grendel (2005)”.
