The character August "Auggie" Pullman in the film Wonder is played by Jacob Tremblay. Tremblay portrays Auggie, a boy with Treacher Collins syndrome, who faces challenges fitting in at school due to his facial differences. To transform into Auggie, Tremblay wore extensive prosthetic makeup that took about two hours to apply daily, including a skull cap, facial prosthetics, a wig, contact lenses, and dentures. His performance is central to the film, which also stars Julia Roberts and Owen Wilson as Auggie's parents
