Amir O'Neil plays Zack Wayne on the new NBC comedy series "Marlon."

Born in Jacksonville, Florida, the 10-year-old moved with his parents and eight siblings to Southern California. The actor, rapper and breakdancer was determined to be on TV and his dream was realized when he and his twin brother, Amari, were signed by The Savage Agency, one of the most successful youth talent agencies in Hollywood.

Two weeks later he and Amari snagged the role of Michael in the TV movie "White Water." Once that wrapped, he was cast as a regular on "Mann and Wife."

Last year O'Neil and his twin had the honor of performing their anti-bullying rap for one of their idols, Stevie Wonder, at the All It Takes star-studded fundraiser at the University of Southern California. Additionally, the boys were featured in the music video for the 2016 Rock Star Recess national elementary school campaign that reinforces safe and healthy play for all children.
