The film was produced in Russia by Rossiya, CTB Film Company, and Melnitsa Animation Studio, and will be released there on April 20, 2017 (which happens to be my birthday). Even though it's a Russian production, it's pretty common nowadays for foreign films, especially animated films, to be dubbed over in English and eventually released in the U.S. and elsewhere. This is the case with the Indian/Mexican animated film Guardians of Oz (Guardianes de Oz), which has been dubbed in English and picked up by Lionsgate for a home video release in the U.S. next month.

I do hope that Urfin Jus is released in the U.S. at some point, even if not dubbed, because it looks pretty good to me. The animation looks nice, the characters are generally well-designed, and it looks overall like a fun and interesting take on Oz, very different from something like Legends of Oz or even Amazon's just-launched Lost in Oz series. Check out the trailer, synopsis, character posters, and some of the newly released stills below, and feel free to leave a comment with your thoughts on it!
The cunning and wicked Urfin Jus decides to become ruler of the Wonderful Land of Oz, take over the Emerald City with his Wooden Soldiers, and rename it to Urfinville. He is all but ready to celebrate victory, when his plans are ruined by Elly — an ordinary girl who ends up in Oz just at the right time. She must return home, but not before she helps her friends — the Scarecrow, the Tin Woodman, and the Cowardly Lion — defeat Urfin. But before they can defeat him, they must find out who he really is.
Update: It looks like the film has already been dubbed in English and is being sold as Fantastic Journey to Oz, a title that could very well change by the time the film reaches us. Animation Magazine's got stills, a trailer, and some more nuggets of information about the film that you can peruse by clicking here.
