She told People: ''I can't say too much about my involvement yet, but I'm very excited to help usher in the strong, empowered female character I helped bring to life, to a new generation. And I'm equally thrilled to see what the original fans think!''

According to Variety, the 'Even Stevens' actress' role will be a cameo.

Meanwhile, Patton is delighted to be returning to his old role of super-villain and mad scientist Professor Dementor.

He tweeted: ''Can't wait for you guys to see this.''
