The duel in The Life and Death of Colonel Blimp represents one of the great choices in cinema, crossing direction, editing, cinematography, and acting.
When the audience expects to see a thrilling, climactic duel, Powell and Pressburger choose to avoid the route taken by other films, from any version of Scaramouche to the various Robin Hood(s) to even The Princess Bride. The duel itself is less important than the build up and the aftermath. The actors knew the importance of the preparation and approach, since the duel itself would barely be seen.
This scene represents one of the most perfect series of choices in cinematic composition, and Criterion's new Blu-ray shows off the whole movie in a manner befitting one of the greatest movies ever made. Scorsese does a marvelous newly-recorded introduction, and Thelma Schoonmaker offers keen insight as she always does on Powell's films. This is one of the best discs of the year, and we're just 1/4 of the way through.
I swear I'll finish a review of this one soon. I've been busy finshing off my monster 2012 Best in Blu-ray multi-list article, among other things.
