For your consideration:
Christopher Lee is one of my favorite Dracula performances of all time; he has the Count's commanding arrogance and predatory disdain honed to a razor's edge.
But as much as I love the Hammer films, particularly Horror of Dracula, his best performance as the Count comes in the lesser-known but more faithful Spanish production "Count Dracula" or "El Conde Dracula".
It isn't 100% faithful and ends up cutting some budgetary corners toward the end, but tell me you don't love Lee getting to finally, FINALLY sink his fangs into Stoker's dialogue portraying a novel-canon Drac.
