The Life and Death of Colonel Blimp (1943) - The Archers considered it their best work, and while it is great cinema I feel that honour should go to The Red Shoes. This one is just a little dated, drags in some parts, and Roger Livesey is a little too over the top in others.
Tenebre (1982) - surely top 3 Argento material here. Been a couple years since I'd seen it and this rewatch was more enjoyable than the first viewing.
