Barbara Hershey has promised that her character in Once Upon a Time is different from the mother in Black Swan.
The actress, who starred in the Oscar-winning film, will appear in Sunday (April 1) night's episode of the ABC series, playing the mother of the Evil Queen (Lana Parrilla).
"I guess the only comparison is that they're both mothers and both love their daughters in their strange ways," Hershey told Entertainment Weekly.
"But the character in Black Swan was really mentally ill, I think," she continued. "And this one is just deliciously evil. It's a fairytale; it's very different."
She went on to speak about her character's relationship with the Evil Queen, insisting it is similar to any other mother-daughter relationship.
"What's interesting to me is that it's like any mother-daughter relationship that's conflictual," Hershey said. "The mother wants something the daughter doesn't want."
Once Upon a Time airs Sundays at 8pm on ABC.
