Back in February, we told you that Relativity Media had signed Oscar-winner Julia Roberts to play the Evil Queen in the Tarsem Singh (The Cell, Immortals) directed film, The Brothers Grimm: Snow White, which is slated to begin principal photography this month.

Now, Deadline reports that Armie Hammer (The Social Network) has signed on to star as Prince Andrew Alcott, and Lily Collins (Priest, The Mortal Instruments) has singed on to star as Snow White.

Relativity’s The Brothers Grimm: Snow White a retelling of one of the most beloved fables of all-time, will eschew the traditional story in favor of a more modern tale full of comedy and adventure. After her evil stepmother kills her father and destroys the kingdom, Snow White bands together with a gang of seven quarrelsome dwarfs to reclaim what is rightly hers.

The Brothers Grimm: Snow White is slated to hit theaters on June 29th, 2012.
