"NCIS" fans may know Muse Watson best from his role as Special Agent Mike Franks, but Watson has also appeared on several other popular TV shows throughout his almost three-decade-long career. According to IMDb, Watson's had roles in "CSI," "Prison Break," "iCarly" and "Castle" just to name a few. He also has appeared on the big screen, famously playing the hook-wielding killer fishermen in the 1997's horror film "I Know What You Did Last Summer," as well as its 1998 sequel. Iconic!

With that impressive resume, it's understandable that Watson continued to work as an actor after his role on "NCIS" ended in 2017. In 2018, he appeared in the short film "Piece," and in 2019 he was in the horror film "The Dead Ones." Still on deck for Watson is the faith-based comedy "Christian Movie" and the drama "Jubilee," as well as the TV mini-series "Diary of a Lunatic."

When Watson isn't acting, he's advocating for those with Autism as the honorary spokesperson for the organization, Stars For Autism. It's a cause personal to the actor since his daughter has Autism. Watson revealed at a 2012 event, "We've made it our life's work to give her all we can." The former "NCIS" star is also very active on Facebook and Twitter, and even frequently responds to fans. While Mike Franks may be gone, Watson appears to have more to give as an actor and advocate!
