Mark Harmon
Mark Harmon is an actor everyone should know. He plays Leroy Gibbs on NCIS and its spin-off series, NCIS: New Orleans. The guy has been in Hollywood for close to 50 years now, and he’s not showing any signs of slowing down.
Just imagine what that sort of stamina and endurance could’ve done for him if he decided to stick to playing football. Instead of following in his dad’s footsteps, he decided to do what his mother, Elysie Knox, did. He did play during high school and college after receiving offers from multiple universities. He even led his college’s team to an upset victory over the reigning champions at that time, the Nebraska Cornhuskers.
