Hi,  I was wondering if there is a character morph for Emma Watson "Hermione Granger" for Laura 3. I am specifically looking for something like from "Goblet of Fire" or "Order of the Phoenix".

I think that's going to be tough to do by searching databases. legally, vendors cannot directly name who a real-life character is susposed to be, so  they  use indirect names, like "London Knights" for Kiera Knightly. Somebody here would just have to know what existing characters fit your bill. You might try searching the forums (instead of the marketplaces) on "Emma Watson" or "Hermione Granger" to see if someone has mentioned a similiarity.  You might also search the marketplace on "Laura 3" and check over the long list for any thing that looked like a code name for what you are looking for.

I actually sitemailed a couple vendors proposing a V4 morph for Miss Watson - While the one felt that the character wasn't to her style, the other vendor said they would keep the idea in mind, and speak with his collaborator on how she felt about it.. so there may be one on the way...

Have you considered trying FaceShop Pro? It's resulted in some amazingly good resemblances for me on several experiments.  It's not too expensive, either.
(I bought it over at DAZ3D, BTW, in case you hadn't heard of it before, and I believe it's also sold at other sites.)

There is this: http://forum.daz3d.com/viewtopic.php?t=63079

I think she's not quite ready yet though.
