I can only comment on One Piece (one of the 
greatest shows currently on tv in Japan!)  It's 
one of the few shows I go out of my way to make 
sure I watch.  Muah hah hah!  They took Ace's 
couple of chapters and extended his appearance in 
the series to several episodes.  Gratuitous, but 
I like it.  ^_^   Uh, anyway. . .

To the best of my knowledge, there are no cels 
for the tv series.  Toei does make and sell 
reproduction cels.  I'd include a link directly 
to the page, but it seems to be down right now.  
You can always check back later http://www.toei-

WAY back a couple of years ago before the tv 
series began, Jump manga produced a half hour One 
Piece video (and some other titles, including 
Hunter x Hunter - if you see Kurapica with orange 
hair you know it's from the promo video) that was 
created with cels.  But I've never seen any of 
those cels for sale or in a gallery (I have seen 
at least one HxH cel from the promo video in a 
gallery, but don't remember where).  

evilminion: The first movie is the one dvd I 
haven't bought yet.  Did they really state that 
they used cels for the movie?  That's weird.  I 
thought Toei had completely weaned themselves 
from cels by that point.  I'm pretty certain that 
the movie from last year (Nejimakijima no Bouken, 
incl. Jango's Dance Carnival) and the new movie 
coming out this year (Chopper/Tyopper Kingdom) 
are completely CG.  There's a really interesting 
section about the creation of Jango's Dance 
Carnival on the DVD for the second movie - I 
recommend it.


Jennifer - who keeps wanting to buy repro cels 
but can't justify it when "real" cels keep 
popping up.  I figure I have a better chance of 
finding another copy of a repro than finding 
another cel in the same sequence for most of the 
stuff I collect.  ^_^
