Firstly, thanks for that very thorough response on the tournaments and knightood. Fascinating. In particular given the notes about _Ivanhoe_ and its influence -- I've only witnessed the A&E production of it, although maybe about time I read it. Seems it might be ripe for ideas.
IVANHOE is well worth a read, although the style is very old fashioned, of course. Still it has some fabulous characters and scenes, and so far as I know the definitive portrayal of a medieval tournament, both melee and joust.
It has been filmed three times that I know of. The recent A&E production had some good moments, as did the older Sam Neill version... the CLASSIC version, however, is still MGM's 50s version, starring Robert Taylor, Elizabeth Taylor, and George Sanders. The jousts are wonderful, Liz is radiant, and George Sanders steals the film as Bois-Gilbert. You should definitely rent that one and have a look.
