When we watch movies, it’s easy to associate actors with the characters they play—both in appearance and personality. That’s why some actors, especially those who wear heavy makeup for a role, can be hard to recognize off-screen.

One prime example is Jacob Tremblay. He rose to fame at a young age with his powerful performance in Wonder, where he played a boy with facial differences. Because of the extensive prosthetics he wore in the film, many fans don’t realize what he actually looks like in real life.

Despite that, Jacob has continued to thrive in Hollywood and build a strong following online. He’s active on Instagram, where he has more than 800,000 followers.

Born on October 5, 2006, in Canada, Jacob grew up in a supportive family. His mom was a stay-at-home parent, and his dad worked as a police officer. Acting runs in the family—both of his sisters are also in the business. His younger sister, Erica Tremblay, appeared in the hit TV show Supernatural, while his older sister, Emma, had a role in the sci-fi film Elysium.
