The use of prosthetics and make-up used to bug me a little, never quite being able to provide a level of verisimilitude necessary and often hurling the actor into the uncanny valley for the duration of the movie.

I might still prefer when actors’ faces are left alone, and it’s all about them recreating a public figure purely through their performance, but the practical effects departments have now gotten so sophisticated that they can create an amazingly strong likeness to real people, to the point where it’s hard to even recognise the actor underneath them.

This is certainly true of Darkest Hour, which sees Gary Oldman take on the role of Sir Winston Churchill. Something about his mouth in the new image is still recognisably Oldman, but otherwise he’s almost impossible to identify.
