Dan Castellaneta and Julie Kavner voice Homer and Marge, respectively, while other cast members include Nancy Cartwright, Yeardley Smith, Harry Shearer and Hank Azaria. The humor andstrangely accurate foresight ofThe Simpsonsremain notable qualities, andafter premiering onThe Tracey Ullman Showin 1987, the animation has changed considerably.
DuringCorridor Crew’s latest video, Silverman revealed why designs for Homer Simpson and other characters transformed asThe Simpsonsprogressed. Check out the video (the explanation ends around 6:54):

Silverman, who also directed several episodes ofThe Simpsons, shared thatanimators didn’t have a model sheet to reference, and that early on, “we took a cue looking at The Muppets.”He noted that they quickly adjusted to a new style, which is noticeable when watching the series back. Read some of Silverman’s comments below:
We didn’t really have a model sheet. So, it was a matter of like, ‘Well how are you drawing Bart this week? How are you drawing Homer this week?’ Yeah, literally it was like that because we had no time to really make a model sheet. Usually it’s the character turned around, like here’s the side view, here’s a front view, here’s a three-quarter view, here’s a rear view and so forth.

We were thinking about the characters, okay yes, they’re of a flat design, but we have to start thinking about them dimensionally. Lisa can’t just have all these random points. We have to start figuring out how many there are and can we design them a little bit more artistically. But actually, if you watch these, especially if you watch or even just skim through them in order, I think you’ll see the evolution, and it took us not too long to get us kind of in the ballpark.
