They did an amazing makeup job making Kevin look old
When Nora opened the door and it showed him i was taken back by how damn good a job they did with the makeup making him look older, it looked so realistic, you could never tell it was a makeup job. Its pretty much what imagine Justin Theroux will look like in his late 50's or 60's.
So props to the makeup effects crew, amazing job, great job on Nora as well, both was so well done.
