William Shatner has been a staple of popular culture for half a century. He is perhaps best known for playing Captain James Kirk on the 1960s television series Star Trek and in more than half a dozen of the like-titled motion pictures that followed. He later served as the omnipresent discount-travel Priceline pitchman and portrayed the lovable lout lawyer Denny Crane on the TV series Boston Legal, for which he won two Emmys and a Golden Globe award. Turn on your television anytime in recent years and there he was, holding court on his cable interview show Raw Nerve, cooing over antiques with the History Channel guys on American Pickers, roasting bad-boy actor Charlie Sheen on Comedy Central, reading Sarah Palin’s Tweets as poetry parody on The Tonight Show, appearing on the CBS sitcom $h*! My Dad Says, awakening the crew of the Space Shuttle Discovery on their final mission or presenting a country music award.
