@bearbearbear:

If you enjoy very British films, here are a couple from the 1980s that I would consider classics:

Another Country (1984)
https://www.imdb.com/title/tt0086904

Maurice (1987)
https://www.imdb.com/title/tt0093512

Many of the films I watch I discover through the "More Like This" feature on IMDB that showcases up to a dozen films.

"The titles listed in the 'More like this' section are generated from a variety of information, including genres, country of origin, actors, and much more."

There are also users' lists on IMDB that can be helpful.

But I raise my eyebrow at the translation.
"Meine Schwiegertochter ist ein Mann" = "My Daughter-in-Law is a Man" not "All you need is love."

It's not a translation but an alternative title.  Very frequently films are given different names for different markets, especially when there is a language difference but sometimes even in the U.S. vs. the UK.

Meine Schwiegertochter ist ein Mann is a German made-for-television comedy for general viewing audiences.  In the U.S., foreign-language films are not considered suitable for the mass market and are released in just a few urban "art-house" theaters plus on DVD or (these days) by streaming.  My Daughter-in-Law is a Man would not be an appealing name for a film with a mostly-LGBT+, English-speaking audience because it is from the viewpoint of the mother.  The chances of an average American seeing this film was almost zero and even for a gay man, there was never much of a chance.  Probably the only way to watch it in the U.S. today, so many years after release, is by torrenting.

and my favourite: The trip

I realise that some of these films are not in English but it's fairly easy to find subtitles for them.

1/  Hellbent.  A slasher horror set in a gay community on Hallowe'en.
2/  My Beautiful Laundrette.
3/  Saved by the Belles.
4/  A Touch of Pink
5/  Zero Patience.
