U.S. Grimmster here. As far as I know, the fans are pretty widespread. I don't know if that's the usual thing with other U.S. shows, but I know we have fans from Germany, the UK, and Australia on the forum here, along with fellow Americans.

Wellcome Rumpelstiltskin and greetings to all Grimmsters around the world!
I am a Greek Grimmster. We watch a lot of U.S. shows on tv networks in my country and I am certain that whenever they decide to broadcast Grimm here in Greece(I hope it's very soon), Greeks will become The Greatest Grimm fans around the globe.
I'm telling every person that I know about Grimm!!!!
Another Germany here *waves*.
Well, I know because of Twitter and my own Grimm-communities that fans are pretty much international for Grimm. A former friend of mine, and also Grimmster, is from Australia, another (current) is from Austria - LOL, she actually lives in the area around Vienna and has relatives there), other ones are from Spain, Italy, Czech Republic, Philipines, Vietnam, Russia, Netherlands, Belgium. There's a big fanbase in Brazil I know (because you are stumbling over them every five minutes via Twitter). My admin at TeamGiuntoli is from UK, another former friend of mine and admin of GrimmFrance is, well, from France .
