Movie with long cast credits and no order numbers

IMDb lists 32 actors for a German movie, of which there are just two online reviews and two Wikipedia pages; the two Wikipedia pages list just 6 actors each (and not even the same, one of them listing an important actress that is not yet part of IMDb listing...), and probably no one in the world cares but me, who believe that this softcore fake documentary that grossed millions of Deutsch Marks back then and opened the way to a series of 6 movies with part of the same crews and actors, is important: (a) from a film industry point of view; (b) for film researchers about several main actors that made it to long and fruitful careers.

2 actresses that appear in those apparent "top stars" in the Wikipedia languages' pages, are neither top stars, nor meriting being dumped in places No.12 and 31.

I believe those two actresses - like all the other 30 in the cast - merit being placed in the only logical possible order: the alphabetical order.

I already know how to re-order the cast, but I wish to have your opinion: is it worth spending my time editing the cast page in IMDb, or will my work be dumped by the automatic checking system with «We have no evidence of that.» Of course Ai can have no evidence, but I do: I facial checked the cast along with their characters, watching the movie step-by-step.

By the way: it is funny, and so decent that it could be passed for a PG these days.

This is the sort of data that has not been kept in official registries (that are not public, anyway) and not even the film and pink magazines of 1971 published the full casts of an entertainment movie like this.

So, is it worth the while to enter the complete ORDER OF APPEARANCE for this title?
