The first clips have landed online for two Sundance 2013 premieres: Chan-wook Park's Stoker, starring Nicole Kidman and Mia Wasikowska, and Francesca Gregorini's Emanuel and the Truth About Fishes, starring Jessica Biel, Kaya Scodelario and Alfred Molina.  Both movies deal with issues of motherhood, though the first clip from Stoker reveals Kidman's character as rather aggressively unstable while Biel's character is merely a dead-ringer for the protag's own dead mother.  Check out both clips after the jump (be forewarned: both clips are annoyingly set to auto-play).

Here's the first clip for Stoker (via Yahoo!):

Here’s the synopsis for Stoker:

After India’s (Wasikowska’s) father dies in an auto accident, her Uncle Charlie (Goode), who she never knew existed, comes to live with her and her emotionally unstable mother (Kidman). Soon after his arrival, she comes to suspect this mysterious, charming man has ulterior motives, but instead of feeling outrage or horror, this friendless girl becomes increasingly infatuated with him.

Check out the first clip for Emanuel and the Truth About Fishes below (via HitFix):

Here's the synopsis for Emanuel and the Truth About Fishes:

Emanuel, a troubled girl, becomes preoccupied with her mysterious, new neighbor, who bears a striking resemblance to her dead mother. In offering to babysit her newborn, Emanuel unwittingly enters a fragile, fictional world, of which she becomes the gatekeeper. Cast: Kaya Scodelario, Jessica Biel, Alfred Molina, Frances O’Connor, Jimmi Simpson, Aneurin Barnard.
