Most of the Arthur cartoon voice cast has been with the show since Season 1 in 1996. Only there have been voice changes for voice actors/voice actresses for Arthur, D.W., Sue Ellen, Brain, George, Tommy Tibble, Timmy Tibble, Vicita Molena, Rattles, Pal, Emily, and James MacDonald during the 11 seasons.
I finally got to see "Buenas Noches, Vicita/Prunella Packs It In" and "Phony Fern/Brain's Shocking Secret" recently (and I saw "Baby Kate - Imaginary Mystery/Strangers on a Train"), especially with Vicita spoofing Dora the Explorer with an African folk tale, Fern and George spoofing an Agatha Christie mystery, Fern's new cell phone, the first appearance of Fern's father, Nadine now becoming Baby Kate's imaginary friend instead of D.W.'s, Brain being called "Stomach", and even Prunella now has her last name revealed - Prunella Deegan!
I sure can't wait for the other Season 11 Arthur episodes to air September 3-7, 2007 with an episode where Binky adopts an orphan girl from China and an episode spoofing "Postcards from Buster" with guest voice Matt Damon.
Also: For season 11, the "Word From Us Kids" mid show segment is now replaced by a "Postcards from You" mid show segment.
