Jerry Doyle (Michael Garibaldi)

This Bruce Willis lookylikey (his first small-screen gig was as an actor auditioning to take over from Willis in a meta episode Moonlighting) had only two screen credits to his name when he landed the role of waggish Security Chief Michael Garibaldi in Babylon 5. A corporate jet pilot and Wall Street stockbroker before becoming an actor, Doyle appeared in all five seasons of the show, but TV roles after were few and far between. Reinventing himself as a blustering right-wing talk-radio host, he led The Jerry Doyle Show on Talk Radio Network to becoming the sixth most popular talk radio show in the US in 2012. Sadly, a lifetime of alcoholism caught up with Doyle in 2016, when he was found dead in his Las Vegas home.
