UPDATED 9/26/2022 When someone mentions Christopher Plummer, it's likely you'll think of him as Captain von Trapp in the 1965 film The Sound of Music. It's hard not to think of him in that film with how intimidating yet handsome he was, so much so that he even enthralled the interests of both Baronness Schraeder and Fraulein Maria. It's easy to see why! But Plummer's acting career started long before that, beginning in 1953. He has long portrayed public figures from ancient history, including Roman emperor Commodus in The Fall of the Roman Empire (1964), Arthur Wellesley, 1st Duke of Wellington, in Waterloo (1970); Rudyard Kipling in The Man Who Would Be King (1975), and many more. What happened to Christopher Plummer? THE HIGH COMMISSIONER, (aka NOBODY RUNS FOREVER), Christopher Plummer, 1968 / Everett Collection Despite all these incredible roles and portrayals, Plummer truly could never live down Captain von Trapp. He has often spoken about the famous role and how he was "a bit bored with the character. Although we worked hard enough to make him interesting, it was a bit like flogging a dead horse.” However, he does acknowledge that it was extremely well-made and perfect for families of all ages.
