Based on Beatrice Colin and Sara Pinto’s novel “My Invisible Sister,” the live-action adventure/comedy follows Cleo, whose science project takes a wrong turn, causing her popular sister Molly to become completely invisible. The accident spurs the introverted Cleo to step into the shoes of her older sister and take her place in an important lacrosse game, while trying to convince everyone that nothing is wrong — while trying to reverse Cleo’s experiment before Molly’s invisibility becomes permanent.
Blanchard plays Cleo, and co-stars with fellow Disney actress Paris Berelc (“Mighty Med”), who plays her sister.
The TV movie also stars another familiar Disney face, Karan Brar — the “Jessie” alum and “Bunk’d” regular will play Cleo’s best friend and fellow science whiz kid George. The cast is rounded out by Rachel Crow (“The X Factor”), who will play Molly’s best friend and teammate; newcomer Austin Fryberger as Molly’s boyfriend; Will Meyers (“Bella and the Bulldogs”) as Cleo’s crush; and Alex Désert (“The Avengers: Earth’s Mightiest Heroes”) as the high school science teacher.
“Invisible Sister” is set in New Orleans during Halloween. The Oct. 9 premiere date coincides with the cable net’s month-long Halloween-themed programming event “Monstober.
“Blanchard’s “Girl Meets World” co-star Sabrina Carpenter is also set to topline a Disney Channel Original Movie with “Adventures in Babysitting,” which is inspired by the 1980s film of the same name. Disney’s “Descendants” star Sofia Carson co-stars in the film, set for a 2016 debut.
“Girl Meets World” was nominated for an Emmy for outstanding children’s program.
