Found the subtitle file. Oddly the film does NOT seem to exist on the IMDb when you search for Domenica, and I couldn't find it on
http://www.opensubtitles.org - which explains why I didn't upload the subtitles I converted a decade ago!
Noticing on this forum it's 2001. I clicked on a film titled Sunday and found the IMDb link here:
https://www.imdb.com/title/tt0245084/
I guess Domenica = Sunday in italian.
Anyway, I joined a sharing site and uploaded the subtitles - both in English and Italian.

If that link doesn't work, let me know a good host, or if it's possible to upload them to the forum. Thought i'd seen someone do that with another subtitle?
