Welcome to Karastan or Lost in Karastan

Screendaily has a report of the near completion of filming Epic which you can read here.  The article goes on to describe Myanna Buring's favourite scene during the filming of Epic.

“We shot this scene, which will stay with me, I think, for the rest of my life – cause if you had asked me, 2 years ago even, if I would believe that one day I would be in a scene where I would watch the fantastic Noah Taylor pretending to hump the wonderful Matthew Macfayden’s leg, I would have told you that you were crazy, but I now have witnessed this. And it’s possibly one of the funniest things I’ve ever seen in my life, and I’m very grateful to Epic that I got to experience that.”

There are more photos from the Frankfurt set visit/press conference that you can view HERE.

In the google translation of this article, he says that after filming Ripper Street, he will "perhaps" do a play.  This is the third article that has mentioned this play, however, so hopefully it is more than "perhaps".  

Redcarpetreports.de has posted photos and a report from the set of Epic. 

As translated by google:

World star Matthew Mcfadyen filming in Frankfurt am Main and Hesse.

Matthew Mcfadyen, best known as Mr. Darcy from Jane Austen adaptation of "Pride and Prejudice", from movies such as "The Three Musketeers" and "Anna Karenina" (but also for example from "Frost / Nixon"), removes the regency costumes and slips into comfortable corduroy jackets and scarves to embody a young director in Ben Hopkins new movie "Epic". But even with scarf, corduroy jacket and backpack on the set in Frankfurt, the charismatic Matthew Mcfadyen never loses his dignified bearing and unique charisma.

And about the filming locations:

Now five days of shooting take place in Frankfurt, Wiesbaden and surrounding regions (for example a castle in Büdingen) and then one day of filming in London

And about the story of Epic

The story of "Epic" is about the award winning film director Emil Miller (Matthew Mcfadyen), invited by the fictional small country located in the Caucasus "Autonomous Republic Karastan" to the local and international film festivals honored here. President Aleluyev (Richard van Weyden) asks him to film an epic story of the national hero Tannat, who earlier lost his mother and was then raised by an eagle (The animal selection of this heroic saga is my personal favorite detail). The director, who notices the grim military in the country, but also the charming President and seductive festival director (MyAnna Buring), begins a journey full of adventures by political and psychological nature, sex and love.
