It's Kristin Scott Thomas, the movie is French though.

She was in a movie called In the House, which was sort of a suspense film, but the first pic makes me think of some fraternity flick. Could be both perhaps?

You're right, it's In the House / Dans la maison (2012) movie. The first screen shows my favorite scene, it's about a boy writing essay about "normal" and since he is a pupil in school he describes his day with his school friend and such.

This one is European too, with international distribution. Fairly recent.

Here's another pic, this will bring it closer to home:

Låt den rätte komma in?

Harry Poter

Nope, but that is an awesome movie.
Nope :)

Three more hints:

1. Released after 2015.
2. In spite of good reviews, was not a box office success.
3. The country of origin shares a border with Russia.

Not sure about 2. but Thelma (2017) would at least pass the 1st and 3rd criteria.
It also features a scene involving the point of view in the second still, if I remember correctly.

Right you are. Well done. Dumping excess pics, and you're on.

Edit: According to Wikipedia, it cost 5.8 m $ to make, and had box office earnings of 1.5 m $.

Apparently, they have tried to recoup the loss (at least a little) by selling off the rights for yet another completely unnecessary and very likely to be butchered US remake last year.

Staying in Europe (but going on a trip) with this one:

Spies Like Us

When I saw the first pic I thought "ah, it's that eastern Europe movie about psychedelic mushrooms with emphasis on horror", the second pic was like "what, Star Wars?"
