How the Simpsons stays fresh

When The Simpsons burst onto television screens in 1989 in the United States, and two years later in Australia, it was something entirely new: cheeky, clever, and just a little bit rebellious. 

Four decades later, Homer’s unmistakable “D’oh!” still rings out across living rooms worldwide, proving that good storytelling and memorable characters never go out of style. 

One of the show’s most delightful quirks is that its characters never age. Bart is perpetually 10, Lisa forever 8, and Homer and Marge remain in their thirties. 

Yet behind those familiar animated faces are performers and creatives who have grown older alongside their audience, adding a layer of meaning to the show’s longevity. 

Today, many of the original voice cast are approaching, or have already passed, retirement age. 

Harry Shearer, the voice of Mr Burns, Ned Flanders, and many others, is now 82. Julie Kavner (Marge) is 75, Dan Castellaneta (Homer) and Nancy Cartwright (Bart) are both 68, and Hank Azaria (who voices a host of characters including Moe) and Yeardley Smth (Lisa) are 62. 

Remarkably, they continue to voice characters decades younger than themselves, bringing both energy and emotional nuance that feels fresh. 

It is a rare professional journey. Few actors begin a role in their 30s or 40s and are still performing it well into their 70s or 80s. 

While technology has evolved dramatically since the series began, and technology could be used to replace the cast or augment their work, the human element remains central.
