There isn't much information but thought I'd give the heads-up on this anyway, especially as it will be, feature length, made in English and intended for distribution to the US, and likely UK and Australia as well.
From Variety:
South Korean sales agency Finecut has picked up international rights to “Red Shoes & The 7 Dwarfs,” an English-language animated feature that is a twist on the classic “Snow White” tales.
The $12 million family-oriented 3D animated project is now in production at Locus Creative Studio, one of the leading animation and VFX companies in Korea. Delivery is scheduled for summer 2017.
Director Hong Sungho describes the film as “tackling the inconvenient truth” about Snow White, namely that the dwarves are knights under a spell and Snow White is no longer the fairest woman in the land.
The screenplay previously won a 2010 Korean Story Competition and sees the dwarf knights on a quest for red shoes which have magical powers, but which are already on the feet of another woman.
The film will be CG and apparently Red Shoes and the Seven Dwarfs is a working title.The film is scheduled to be released in the Summer of 2017 in Korea so, with news reaching Variety like this, there's a chance the US will see it in the same calendar year as well. Maybe.
