Rob Riggle
Being a marine is one thing, but rising up the ladder to become a decorated lieutenant colonel and then quitting your job to pursue acting is a whole new level! It is the true story of Rob Riggle, the man who played Mr. Walters in 21 Jump Street and its lauded sequel 22 Jump Street.
Even after quitting the Marine Forces, Riggle kept in touch with the military and defense world. Most famously, he went to Iraq as a member of the USO to entertain the American troops with his wit and charm.
