Elizabeth's (non-)smoking and an odd resemblance
Just finished a second viewing after a decade or so, and enjoyed its premise and thriller aspects just as much, with Noah Emmerich and Frank Langella being standouts, imo, but other bits less so, so this will likely be the last go-round for me. Anyhoo, two things leapt out at me:
Why would they make smoking such an integral part of Elizabeth's character, when Keri Russell couldn't smoke a cigarette convincingly to save her life? I can generally suspend disbelief about certain inaccuracies enough so they don't bug me, but she just looked so unnatural holding a cig and obviously not inhaling the smoke; just make her a non-smoker and leave it at that.
And this might sound weird, but once I noticed it, it became a point of distraction: to my eyes there is a strong facial feature resemblance between Julia Garner (Kimmy) and Brandon J. Dirden (agent Aderholt). Absent the sex, size, skin tone, hair and mustache differences, they're dead ringers.
