Kristen Stewart is circling the role of Snow White and Viggo Mortensen has signed on to play the Huntsman in Universal's Snow White and the Huntsman, reports Heat Vision.

Director Rupert Sanders is in deep casting mode, and has gone through a series of screen tests with such actresses as Riley Keough, Felicity Jones and Alicia Vikander. Emily Browning tested this past weekend. Kristen Stewart is one name they keep coming back to.

An original retelling of the Grimm fairy tale, Snow White and the Huntsman centers on the huntsman (who, in the original fairy tale, is supposed to kill Snow White but ends up letting her go) becomes her protector and a mentor of sorts as they try to escape from the evil queen who ordered her death. Charlize Theron is in negotiations to play the evil queen.

The film is set to shoot sometime this summer for a Dec. 21, 2012, release.
