Christopher Lee at the count from Dracula Has Risen from the Grave.

From Wikipedia:

Dracula Has Risen from the Grave is a 1968 British horror film directed by Freddie Francis for Hammer Films. It stars Christopher Lee as Count Dracula, with support from Rupert Davies, Veronica Carlson, Barry Andrews, Barbara Ewing, Ewan Hooper and Michael Ripper.

The world of the film is arguably far darker and more ambiguous than the world created by director Terence Fisher for the previous three films in the Dracula series.
