This is certainly true of Darkest Hour, which sees Gary Oldman take on the role of Sir Winston Churchill.
Darkest Hour is being directed by Joe Wright (Atonement, the ‘Nosedive’ episode of Black Mirror) and co-stars Lily James, Ben Mendelsohn and Kristin Scott Thomas.
Something about his mouth in the new image is still Oldman, but otherwise he’s almost impossible to identify.
The use of prosthetics and make-up used to bug me a little, never quite being up to standard and often hurling the actor into the uncanny valley for the duration of the movie.
