Video Director based in Central Arkansas. At the moment, I shoot a lot of music videos. However, I've also done some commercial & promo video work.
I would assume being a foreign director would help someone standout. The biggest issues would be getting over the cultural barriers that might make it harder for a US audience to understand your film. Other than that, I would think US agents/managers/film festivals would welcome foreign directors. Not all, but many Americans already watch a lot of foreign films. And if you're talking about tailoring your films to an American audience, even better. As much as I love watching Korean films, it would be cool to watch them without having to read subtitles the entire time lol. As far as not being used to American production processes, I assume you'd be in the same situation as any American filmmaker who hasn't worked with a large crew and has never done a feature before.
This is good advice and interesting. Around 2010-11 I started to lose interest in film festivals as a path for new/young filmmakers to break into the film industry. I assumed that the internet would be a much better way to present your film, build an audience and a following. Mainly because I assumed that the end game of a festival was to sell your film or get noticed & have a better chance at getting your film in a larger festival. The "festival circuit" didn't seem appealing if only cinephiles (as opposed to the masses) would be in the audience. However, it seems that the festival circuit could offer a lot more in networking besides meeting buyers (who I assumed wouldn't be interested in short films) and other filmmakers who are in the same boat as you.
