One scene that always stands out in the memory is when Kara and Brother Gilbert return to her village to try and rally support for a rebellion. The locals are unimpressed... until Bowen, recovered from his Heroic BSOD, returns on horseback and rides up to the crest of a nearby hill just in time for Draco to soar up, silhouetted against the sky. The image is striking enough to appear on the VHS and DVD covers◊.
The recitation/affirmation of the Old Code in the rain.
"A Knight is sworn to Valor"
"His Heart knows only Virtue"
"His Might upholds the Weak"
"His Blade defends the Helpless"
"His Words speaks only Truth"
"HIS WRATH UNDOES THE WICKED!"
The fact that the effects for Draco still actually hold up after all these years, especially the incredible detail they used with his facial expressions, body movements/mannerisms, and even how his eyes follow the real people around him perfectly. Combine that with Connery's excellent voice acting and you've got one of the most unforgettable dragons on film.
