Karen Gillan and Taissa Farmiga have been tapped to star in director Ti West's Western revenge thriller In a Valley of Violence.

We first reported on the project back in March, when John Travolta and Ethan Hawke signed on to star. The story centers on Ethan Hawke's character, a drifter who arrives in town seeking to avenge the death of his best friend. Karen Gillan and Taissa Farmiga will play sisters who run a hotel in the town. It isn't immediately clear who John Travolta is playing at this time.
