This is all the TV and Video info I could find.

The Redwall television series has been co-produced by Nelvana of
Canada (65%) and Alphanim of France (35%). It consists of 13 half
 hour episodes which recount the original Redwall story and remain
faithful to the book.

The original artwork used as models for the animators has been
painted by Fangorn (aka Chris Baker), the artist who provided most
of the book covers for the British editions. European style animation
was used, similar to the television shows Rupert and Babar which are
shown on CBS and Nickelodeon in the USA.

The TV series will be released in Canada in the Fall of 1999 on
TELETOON, Canada's premier animation station. TELETOON is
presenting a "teaser preview" of the first four episodes in May. They
will be shown May 11, 12, 13 and 14 at 7:00 pm and again at 10:00
pm. These four episodes will then be shown again Saturday May 15
in a marathon from 7:00 to 9:00 pm.

The TV series will be shown in France the thirteen days just before
Christmas 1999, one episode per day.

Nelvana distributes its shows to 160 countries. It is expected that the
the Redwall TV series will be distributed worldwide, and will be
available on video. Additional information will be posted here as it is
released.

Work has just begun on the first Redwall movie, "Martin the
Warrior". Brian Jacques has just begun writing the screenplay himself,
to ensure that the integrity of the book is retained, and the values of
Redwall are maintained. European-style animation will be used, again
with the artwork of Fangorn as models for the animators.
