Sorry…. but it was pretty much made up.  In most versions their relationship is often described as one of mutual loathing but I don't think that's quite accurate either.  Theirs was an arranged marriage and they'd only been married a couple of months before events overtook them so I kind of see them as more never really getting to know each other.  It's true that Jane would not have Guildford crowned as king (a strong independant streak?  ) and that he went and whined to his mother – who was not at all happy!  Yet on the other hand, Guildford asked to see Jane before they were executed but she refused on the grounds that as they were soon to be together in heaven there was not much point.  Which I kind of think is a little harsh….

Jane did though sob out his name though as the cart carrying his body went past the window she was looking out of.  And she always signed herself 'Jane Dudley' so perhaps her marriage wasn't quite as odious to her as most people seem to think, if not quite the love-match as portryed in Lady Jane.  

But don't let that interfere with your enjoyment of the movie; I like it myself!
