Fylm The School Teacher 1975 Mtrjm Awn Layn - Fydyw Lfth Link

I’m not sure what you mean by "fylm The School Teacher 1975 mtrjm awn layn - fydyw lfth" — it looks like a mix of transliteration or garbled words. I can still help, but I’ll pick a reasonable interpretation and produce a substantial digest. I’ll assume you mean the 1975 Italian film "The Schoolteacher" (original title: "La supplente" / "L'insegnante") or one of the 1970s Italian "Insegnante" series (commonly translated as The Schoolteacher), and that you want a thoughtful, well-written analysis/digest in natural tone.
