The reason is because there was no name change and the voice is unknown. That chart is only for identified actors or name changes for translation, or both (when there's neither, we leave it out). Many characters appeared who aren't in that list because the info isn't known.
The only way it would work is in a brief text list (not part of a voice cast chart) of other characters. If you know enough to make it interesting, feel free. But as is, it doesn't work in the chart. Also, the link you added was non-existent (that is, there's no Sweden section on International Elmo precisely because there was no name change or known voice performer; the list isn't exhaustive, but meant to track instances where we have specific info, beyond the character appearance).
I went ahead and added a brief note to the top of the page that the 1990s series included newer characters such as Elmo, so for now, without a voice actor identification, that's the best way to handle it. I hope that explains the change (sometimes administrators get into the habit of reverting, when we often have to deal with vandals and such, and forget to explain why when the reason isn't obvious to someone not familiar with our structure or formats, sorry!)
Hi! Take a look at Category talk:Creature Shop Movie Actors, which explains Henrik's reverts and deletes. Basically, we don't create a page for an actor in a movie where the Creature Shop only provided effects or puppets for a sequence, especially after the sale of the Muppets to Disney (since that remains our main focus; we had a huge discussion of that awhile back). Russell Brand has no scenes with any of the puppets. We don't create pages for people who produced movies where the Creature Shop provided effects either (as opposed to those actually made by the Henson Company) so Judd Apatow will likely be deleted, unless the audition note can be better sourced and the page expanded. You had no way of knowing, and we appreciate your effort, but basically Forgetting Sarah Marshall is one of those projects where we try to cover the info on one page and actors with no other connection won't get their own page. Adding the credit to other pages, like Steve Landesberg (which I've been needing to beef up and revise anyway; he passed away, and that's not on there) is fine, but not the category.
I know that's all confusing to a first time editor, but I hope it explains things. Thanks, and don't be discouraged!
Yeah, that was a deleted scene or possibly a deliberate "made for the DVD" extra, we're not sure the Creature Shop made it (though probably), and the picture's on the page. There's just no need to make a solo page for him at this time.
Hello! I saw that you removed Jason Segel from the Creature Shop Movie Actors category because Forgetting Sarah Marshall is "a Creature Shop effect film not a Creature Shop produced movie, therefore no Creature Shop movie actor tag is needed." I don't understand. Eddie Murphy is in the Creature Shop Movie Actors category, and Dr. Dolittle was also a Creature Shop effect film, not a Creature Shop produced movie. And John Goodman is in the category and The Flintstones was also just a Creature Shop effect film.
Ok, I understand removing Steve Landesberg and Jason Bateman from the category because they didn't interact with any Creature Shop provided characters. But now I am confused again because Jason Segel and Bill Hader clearly interacted with the puppets. How are they not qualified?
Creature Shop Puppeteers works (I'm glad you added it to Hader, that was just an oversight) since really that's what the whole sequence is, they're putting on a puppet show, with the puppeteers visible and the fact that they're puppets made obvious, not interacting with Creatures meant to be actual living characters within the movie. We don't categorize Drew Massey, in the same scene, as a Creature Shop Movies actor either.
