First thing to come to my mind was
Yobi, the Five Tailed Fox. It is actually Korean, directed by
Lee Seong-kang who also directed
My Beautiful Girl Mari, another Korean film. It is posted on
AniDB but not on
ANN.
Next came all the
Sonic X episodes my daughter Jenny watched in French from
Jetix because, let's face it, the
4Kids version sucks.
My first viewing of
The Borrower Arrietty was a low quality French dub camera rip from a French movie theater, without English subtitles. I now have the Japanese Blue-Ray DTS version with English subs.
Until
Project Kitteh finally subbed the last 10 episodes in English, I watched the final episodes of
Ashita no Nadja on
YouTube and
Hulu in French or Spanish.
My most recent would be my attempts to get
Yawara! in English. I only recently found the last half of the series in a crappy English sub. Prior to that it was in Catalan or Japanese with no English subs. To this day I still don't understand why nobody has finished subbing this! When it first aired it was up against Ranma 1/2 and actually was getting better ratings! The three subbing groups that are currently collaborating on this show just make me want to scream in frustration!
SLOWER THAN A GLACIER, is an understatement. At their current pace, they will finish subbing this around 2023 or so, if they hurry. It is more likely to be 2040 something. (OK Wuntvor cool down, take deep breaths.)
As far as I know
Watashi to Watashi: Futari no Lotte, known by most of us as
The Parent Trap, still isn't available in an English sub, but can be watched in French, Spanish, or German on
YouTube and
Hulu. I hope that some day
Licca Fansubs will sub it. They are doing
Pollyanna now.
