Campaign prep for A game in england 1067

I am currently preparing to run a game with new players at my university. I plan on a werewolf game set right after William the conquerer takes power but while england is destabilized.

Quick recommendation.  Find a useful source or few sources.  Read them.  Agree with players that those are references.  Keep them short enough to not have too much hidden and from there %$#@ history.

Too often I see games get bogged down in "well, I looked this up and that couldn't happen because a blacksmith in 1069 registered a land deed and Williamshire and it said that ...." 

Blech.  Frak.  Zorn.  It.  All.  To.  Heck.  And.  Darnation.

Don't let facts stand in the way of a good game.  It's good to have common ground that can give players a feeling of security, of knowing they have room to work in that won't get pulled from under them.  It's another thing for the Storyteller to not have room to work in either.

Ok sounds good. I picked up a few history books on the subject and have been reading up on the battle of hastings. Are there any good movies or tv shows of this time period?
