Excalibur (1981)
Nicholas Clay plays Lancelot. What makes the film unusual is that Boorman shoots the legend as the legend instead of as a historical drama.
Director: John Boorman
John Boorman directed Deliverance, Point Blank and Excalibur, and was nominated twice for Best Director. Hope and Glory drew directly on his own childhood in the Blitz, and he has written several volumes of memoir.
