Hello, I have the bluray set of LOTR trilogy
https://www.blu-ray.com/movies/The-Lord-of-the-Rings-The-Motion-Picture-Trilogy-Blu-ray/31196/
however, I have to double check, I believe beside the English audio tracks, the French dub is available. I will check after work and let you know what are the other dubs, if any, would that work?
