Ben Affleck in The Accountant.
It's a pretty bog standard bourne-style espionage thriller with the gimmick being that the protag's day job is as a forensic accountant, tracing money from terrorist organizations. It's highly ciche and competently made, but you've seen this story before.
Except for Affleck's portrayal of aspergers, which is dead fucking on. I mean that shit is PERFECT. I have asperger's myself and honestly the movie is hard for me to watch because every time he's on screen he does some subtle little tic or quirk that I not only do, but he does it in the right context. I keep seeing things in his performance that I see in the mirror every day, or hear him say things in a way that I say them. The whole thing causes this weird out of body experience for me because I'm looking at all this familiar shit, but it's coming form the dude who played batman. It must have taken meticulous research.
It also elevates the film itself which engages is quite a bit of that whole "non neurotypicals are superpowered" thing that hollywood loves. And there are a few tics to his character that were clearly scripted in because they don't come off naturally at all, when every other aspect of the performance feels natural. Even the social awkwardness feels authentic. You can literally see the seams in the movie where affleck's oscar level performance is meeting with the B grade script and direction and it is jarring as hell.
