“Fancy Nancy” is about to step up her game in a wide-ranging deal with Disney.

Disney Junior has cut a deal with HarperCollins Children’s Books for rights to the hugely successful book series about a plucky little girl who likes to be “fancy” in all aspects of her life. Disney Junior plans an animated telepic and series adaptation, targeted to premiere in 2017. The pact also calls for a host of merchandising tie-ins to be handled by Disney’s formidable consumer products operation.

“Fancy Nancy,” created by Jane O’Connor and Robin Preiss Glasser, has spawned more than 60 books that have sold some 28 million copies. The property has been chased for film and TV adaptations in the past. Shawn Levy and 20th Century Fox had been developing a “Fancy Nancy” feature, with Tina Fey also attached to produce, but the project is no longer active.

Disney Junior chief Nancy Kanter and HarperCollins Children’s Books president-publisher Susan Katz unveiled the deal on Friday. Katz noted that “Fancy Nancy” is marking its 10th anniversary this year.

“We are very eager to give her an even bigger stage on which to perform,” Kanter said.

Creators O’Connor and Preiss Glasser said Disney was a natural partner for the property aimed at kids 2-7, which aims to emphasize the importance of self-expression.

“This is definitely one of those ‘pinch me’ moments. When Robin and I met Nancy Kanter and her team, we knew instantly that Disney Junior was the plus-perfect home for ‘Fancy Nancy,’ ” said O’Connor.

Added Preiss Glasser: “After the thrill of seeing my two-dimensional drawings of Nancy and her ‘world’ come alive in spinoff musicals and ballets, the opportunity to see her animated by Disney is a dream I never would have dared to dream.”
