Just on the basis of the casting alone, I'm interested! 
Sarah Bolger from The Tudors (Mary Tudor) doesn't seem young enough to play Miranda Otto's daughter but according to IMDB, amazingly Otto is 24 years older than Bolger. I would have guessed they were much closer in age.
(If that's the Sarah Bolger they're referring to). Bolger is also a very interesting actress, and I wish they'd keep The Tudors going into Mary Tudor's reign.

Nick Stahl has joined the cast of Fox's drama pilot Locke & Key, which was originally targeted for summer but is now for fall consideration.
...
It tells the story of Nina Locke (Miranda Otto) and her three children, Tyler, Kinsey (Sarah Bolger), and Bode who, after the brutal murder of Nina's husband Rendell Locke, return to Keyhouse, his old family home in Massachusetts. There, they are pestered by an evil entity named DODGE that's determined to hold the family hostage one way or another until it gets what it wants. Stahl will play Rendell's younger brother Duncan Locke, an art teacher, who lives nearby and frequently visits Nina and the kids and who strangely has few memories of his time growing up in Keyhouse.
