"Brother to Brother, in life and in death…" My first contact with King Arthur and the Round Table onscreen was with Disney's The Sword in the Stone (1963). The second one was with this film by Jerry Zucker: First Knight (1995, aka Lancelot - First Knight).
In this supernatural-free version of the legend, King Arthur, aged and war-weary, is forced to leave Camelot one last time and fight against the evil traitor Malagent. Lancelot, in turn, is a free-living peasant who uses his sword ability as a way of living. After saving Lady Guinevere from an ambush engineered by Malagent, he falls in love for her at first sight. This leads to a romantic triangle comprising comprising Arthur, Lancelot and Guinevere, a triangle of which the king is unaware.
The film made me grow up with the idea of Sean Connery as King Arthur, Richard Gere as Sir Lancelot and Julia Ormond as Lady Guinevere. Understandable!
