The film series, which ran from 2015 to 2019, starred the trio as the children of Disney villains like Maleficent and Jafar. Cameron had portrayed Cruella de Vil's son Carlos.

Also in attendance at the benefit: Adam Sandler, who played the actor's father in the Grown Ups films. He walked the purple carpet in a casual attire, flashing a peace sign.
