Questions About Beowulf

I regard Robert Zemeckis as a master storyteller. His screenplay for Back to the Future, co-written with Bob Gale, is nothing short of perfection. That being said, I do have several nagging questions about his new movie Beowulf.

1. Why was Brundle-fly so angry? And why did he sound like George McFly?


2. Why did Beowulf take off his clothes for his first battle with a dude, but when Angelina Jolie came at him wet and naked he left them on?


3. Why didn't Santa help fight the dragon?
