Shashawnee Hall
For Shashawnee Hall, acting on the set of JAG was certainly not the end of the road. He made guest appearances in NCIS, acted in Lie to Me, The Closer and Medium, and even had parts in Bruce Almighty and Evan Almighty. Today he is also a successful producer.
Ned Vaughn
Although you probably do remember him as Lt. Carl Barrett from JAG, it was actually the fourth season of the show 24 that got him his high acting status. Following that show, he starred in many others, some of which include Cane and Commander in Chief.
