If you're doing that period, you're most likely looking at Chain mail, and even scale mail (overlapping little plates) Norman Conical helmets should work, (think Sutton Hoo, or something along the lines of a conical helmet with a noseguard), no surcoats (not invented yet), lances are more like long spears (sometimes even held above the shoulder).
Look for images of the Bayeux (sp?) Tapestry, for reference, etc on Google. Maybe some of the 1st Crusade, Viking (towards the end of their wanderings, but still contemporary) stuff..Byzantine art (like the Alexiad..etc). good luck..animation is completely beyond me..;)
I think Ivanhoe was more 11th-12th century armor, or even later..if it's the one I'm thinking of, Elizabeth Taylor as a young girl (the Jewish character..this was a long time ago..;) it's on the cable channels every now and again.
Don't mind all the historical stuff if it's not really important to the plot, etc..just hope this helps..

I wish I'd said that.. The Staircase Wit
