There is something about old silent movies that becomes increasingly so exquisitely special with time. that part of The Lodger is so imaginative and clever Sprocket, and I love the echo of it near the end, when the love struck bobby with even more eyeliner than The Lodger (who said guyliner was a contemporary thing) and the incredibly freaky (in the best possible way) eyes, has his vision in the footprint of 'the culprit'. Even more though I love the use of shadows, windows and mirrors very very cool!
