"Frozen" is taking over "Once Upon a Time" with the casting of Anna, Elsa and Kristoff, but rumors of ABC taking their storyline into a spinoff might not be the case.

ABC recently announced Georgina Haig will play Elsa, younger sister Anna will be played by Elizabeth Lail and actor Scott Michael Foster is Kristoff. "Once Upon a Time" hasn't revealed how the characters will be integrated into the story line, but ABC President Paul Lee claims there are no plans for a spinoff, for now.

"We don't have immediate plans for a Frozen spinoff, but they're so inventive, those two..." Lee told E! Online, referring to producers Adam Horowitz and Eddy Kitsis. "Eddy and Adam are endlessly inventive, so they have glints in their eyes of stories that they can spin for years to come. So it certainly doesn't rule out their ability or my ability to go beyond Once."

Lee added he doesn't believe it isn't too soon to adapt "Frozen" into a live-action format.

"Frozen is a wonderful asset," Lee said. "John Lassiter (executive producer of the Frozen film), himself flew up to Vancouver, he's integrally related to the way we're doing that. Adam and Eddie always have a twist on every story, so you can imagine their twist is going to be very different. But no, I think it's the perfect time. We're thrilled with it."

However, some fans were concerned the show would turn Queen Elsa into a villain. Producers Adam Horowitz and Eddy Kitsis recently spoke to TV Guide about the villain rumors, assuring fans Elsa won't be turned into an evil character.

"The thing we loved so much about that movie, among a million other things, was that Elsa was misunderstood," Horowitz told TV Guide.

"She was never a villain," Executive Producer Edward Kitsis added.
