English to Russian Art/Literary Poetry & Literature Colloquial Narrative

Greetings

Please, how do you say ‘brimfull’ in fairly colloquial speech, i.e. ‘completely full up’ (in the case I have in mind of a town being full to the brim of people i.e. totally and utterly crowded out)?

In a film I saw (actually a dubbed Russian version of "The Jesus Film"), to express the idea of a town being brimfull of people, it seemed to be saying something like this:
Город был пыполно (быполно?) народу.

Does this ring a bell? Do you have anything like that in Russian? I mention this as it may be relevant – please ignore if unhelpful.

Best wishes, and many thanks,

Simon
