Fan community for FX's The Americans

There do seem to be some videos etc. online, at least. But then, you could probably get a lot out of just watching how they do it on the show and use that. The stuff they do is pretty clear in terms of what they're doing. I remember on an anon meme someone randomly mentioned that they thought the fighting on the show was some of the best on any show, because it was the most like real fighting.
