LaMonica Garrett

Former pro Slamball player LaMonica Garrett is another performer who played two roles in the “NCIS” franchise. He first starred in the original series as a Marine captain before being cast again for “NCIS: Los Angeles” in a one-off role as Michael Williams.

While it’s likely easy to miss him in those prior stints, you’ll remember him if you saw Garrett in other shows like “Sons Of Anarchy” and “Designated Survivor.” He has also landed a recurring role as Mar Novu from 2018 to 2020 in the DC Comics adaptations “Arrow” and “Legends Of Tomorrow.”
