Rumor: Rachel McAdams Attached to The Orphanage Remake and Shirley Jackson Adaptation
I say that because the source also revealed to me that McAdams is attached to the Michael Douglas produced We Have Always Lived in the Castle, an adaptation of a 1962 Shirley Jackson novel. Horror scribe Mark Kruger penned the script, which is a horror story that revolves around the Blackwood Family -- two sisters and their uncle -- forced into seclusion after the poisoning of several of their family members. Complications arise when a dubious long lost cousin arrives to secure the family fortune.
In addition to McAdams, Saoirse Ronan is apparently attached as the other sister, while Michael Douglas is set to play the uncle. If, in fact, both of these casting stories pan out, that'd put McAdams in two horror movies. It's possible that she is attached to both but may drop out of one before the cast is set. We Have Always Lived in the Castle is still searching for a director.
McAdams is also attached or rumored to be in a Terrence Malick project, a Woody Allen movie, and a movie based on the life of Elliot Ness. I'd also expect her back for the Sherlock Holmes sequel.
