The production company, Seattle-based Imagen Films, informed me via email that they were indeed developing a Redwall film.
However, when I met with Brian Jacques last October, he seemed uncertain of what I was talking about when I mentioned the movie.
Now, approximately a year from when we announced the existence of the film, the redwallthemovie.com website is down, and has been down for several weeks now. The domain is still registered through September 2009, though.
Imagen Films has failed to return inquiries for comment on this issue, and one is left to wonder, is the Redwall movie still going to happen? I guess it remains to be seen, however like other Redwall film ventures of the past, it's not looking good.
