David Alexander McPhail (11 April 1945 – 14 May 2021) was a New Zealand comedic actor and writer whose television career spanned four decades. McPhail first won fame on sketch comedy show A Week of It, partly thanks to his impressions of New Zealand prime minister Robert Muldoon. He went on to appear in multiple series of sketch show McPhail and Gadsby, and hit comedy Letter to Blanchy. All three shows featured his longtime friend Jon Gadsby.
