I'm not that great either.
I think I only noticed because I watched the movie with the director commentary, and they mentioned the stunt double at that part. They also mentioned how Cillian's eyebrows were thinner in some parts and not in others because he played a transvestite for
Breakfast in Pluto before he came to film
Red Eye, so his eyebrows were still nicely plucked in some scenes.
Whenever I watch the movie now, I notice it.
