Of course eventually I figured it out when they did various closeups of the actors faces and they looked a bit like Tim Allen's Santa robot in The Santa Claus 2. :-)
Anyway, this trailer is different from the one that's over at Apple.com. This is the one that folks have been talking about online due to showing Angelina Jolie nude. Of course considering the perfect abs they gave to actor Ray Winstone, you probably shouldn't get too excited about the fact that it's a naked Angelina... no doubt they did a fair amount of "enhancing" to her as well.
For those of you who don't know, not only will Beowulf be released in 3D, but in IMAX 3D as well (guess which version I'll be watching).
