Madeleine Stowe and Henry Czerny have signed on to co-star in ABC's drama pilot Revenge.

The show centers on Emily Thorn/Amanda Clarke (Emily VanCamp), a mysterious woman who comes to the Hamptons to exact revenge on the Graysons who destroyed her family.

Madeleine Stowe will play Victoria Grayson, the matriarch of the family and a social power broker. Having long ago masterminded the merciless destruction of Amanda's dad Kevin Clarke and the ostracism of his daughter to a life in foster homes, Victoria has no idea that Emily is actually Amanda and welcomes her as a friend and neighbor. Henry Czerny will play Victoria's husband Conrad.
