Yes, some good description here in the Wiki page, and also others I read elsewhere last month that provide various details of the film's narrative and the unexpected twists and turns that came about for the main character. One such detail that surprised me was when the moment arrived to make final arrangements for RIII's final interrment, and who should also step forward requesting to be considered but York Minster? As a descendant of Yorkshiremen myself this made me smile somewhat, even if the king's reburial was eventually at Leicester Cathedral.
