Ok, the movie will, if it’s like the novel, be quite dark, so Dakota’s role seems assured to be heavy.
The two girls are Alice and Ronnie. IMDb has very little at this time, so I don’t know which one Dakota plays or what her character’s involvement is. Of course, I’m hoping that Dakota gets to play a psychopath; it would be a superb and, IMO, a difficult challenge to play a real one. It hasn’t even been tried very often in Hollywood. Two classics that I know of in this genre are “The Bad Seed” (1956 and 1985) and “Shadow of a Doubt” (Alfred Hitchcock/Joseph Cotton/1943). I have no idea whether the screenplay goes this far or not, but I have hope – or maybe just fanciful wishes – for Dakota? I’m basing this hope on the fact that one of the girls is also a “gifted liar,” which is, to my knowledge, a characteristic of psychopaths. Also a hopeful indication, the novel seems to focus on good psychological characterizations. A great performance in a (rare) great role could put Dakota up for an award; that’s exactly how Foster, Theron, and Portman did it.
I found some enticing clues about this stand-alone novel among the 5-star buyer reviews at amazon:
“…deeply psychological page-turner with marvelously descriptive writing.”
“As the story unfolds, a tale of psychological horror emerges that is truly chilling.”
“Her portrayal of Alice’s mother is fascinating, as well as her depiction of the former, then present, mental states of Alice and Ronnie.”
“All the characters are incredibly well developed and 100% believable.”
“Its impact lasts long after the final page is turned.”
Really, I find this to be the most exciting piece of Dakota news I’ve seen for more than a year. I’m skeptical about the Errol Flynn pic (filming right now in Atlanta, I believe), but not about “Every Secret Thing.”
