Recently Kristin Bauer van Straten posted on her facebook page:
I’ve been very busy shooting Once Upon a Time as #maleficent – sorry I haven’t posted too much on FB.
She returns to Once Upon A Time when her character Maleficent, one of The Queens of Darkness, along with Cruella De Vil (Victoria Smurfit), sea monstress and Ursula (Merrin Dungey) become the main villains of the second part of Season 4.
Cruella de Vil will have magical power “that deals with animals“, and the Queens of Darkness will all have “a very interesting connection” to Snow White and Prince Charming.
Look for Kristin when “Once Upon A Time” Season 4 returns on March 1 on ABC.
