Music and movies from the PRL times in Poland

Can you please recommend some iconic Polish movies/TV series from the PRL?

(I prefer comedy movies or those showing real life issues, not much into dark/creepy ones with OTT drama)

Also, what were the huge pop stars in the socialist times? Did they also do Polish covers of Western songs? (like for example the Czech cover of Smokie's Oh Carol called Oh Harold).

What I remember the most is the Alternatywy 4 TV show - very famous and great series (about reality in Poland's PRL)
Beside that my favourite movies were those directed by Stanislaw Bareja - great comedies with fabulous actors.

Miś ( teddy bear ) is probably one of the best known Polish comedies. I really liked it. It's on YouTube if you want to watch it.

Here is a link to Polish comedies of the time, and you can read about Miś there:

Yes, my cult film, too. Never tired of watching it.

Other cult comedies - e.g., trilogy of two peasant families`, Pawlaks and Karguls, feud. First episode - Sami Swoi. Hey, come to the fence, like I am.

'Krzyżacy' (Teutonic Knights)- the first Polish superproduction. The battle scene - a medieval one so both sides sing religious songs.

The actor who played the Polish king in the first movie also played the German officer in the second one -wonderful Emil Karewicz.

There are lots more. I hope more people will get involved :)
