Deletion of V.I.P. (1991 film)

Comment: I found a mention of this in 1991 Polish mainstream magazine Wprost https://books.google.co.kr/books?id=piTtAAAAMAAJ&q=V.I.P.+film+polski+1991+-wikipedia&dq=V.I.P.+film+polski+1991+-wikipedia&hl=en&sa=X&ved=0ahUKEwjivJX709nlAhUD_GEKHboCDwQQ6AEIRDAD but it's snippet view and I can't verify right now if it is in-depth or in-passing. Searching for the main character name in books gives two more hits (https://www.google.com/search?rlz=1C1CHBF_enKR705KR707&biw=1920&bih=1007&tbm=bks&sxsrf=ACYBGNSYxspOi04vV--LEN9AgSanhOd96A%3A1573183159629&ei=t97EXaKFJoP4hwO6hbwg&q=%22Roman+Natorski%22&oq=%22Roman+Natorski%22&gs_l=psy-ab.3...167075.167539.0.167732.3.3.0.0.0.0.152.391.0j3.3.0....0...1c.1.64.psy-ab..0.0.0....0.7lQTVKNhffo) that are clearly about this movie, but again due to snippet view I can't verify what they are, in depth or in passing. One appears to be a script or a book that this was based on? I cannot be certain. I see some mentions in passing in Google and Google Scholar, but I could't find anything in-depth. However, Machulski is a major Polish movie director, and and while , the odds are this work has some reviews in 1991 newspapers and such. But generic title of the movie doesn't help, and a lot of 1991 papers etc. are either not digitized or I don't know how to look for them. I'd be leaning keep, honestly, becausde ITSHOULDBENOTABLE, but OI can't produce proof. PS. A bit more digging: https://books.google.co.kr/books?id=ElRIAQAAIAAJ&q=V.I.P.+machulski&dq=V.I.P.+machulski&hl=en&sa=X&ved=0ahUKEwjDsOmP19rlAhXk-GEKHULvANYQ6AEINzAC this book has at least a paragraph and it looks more like an entire page or two about this movie (snippet view only, but I can see a page heading and some text). On the assumption that this has at least two pages in-depth treatment in said book I've changed my vote to keep. In 1991 this probably got press reviews in Poland and such, but this stuff is effectively unavailable unless one goes to a Polish  library and looks at old newspapers. But I see some mentions in passing, at least, plus such content as in this book, and I am pretty sure that there is enough to write some sections on reception and significance, if only someone was willing to spend hour sand hours digging through undigitized Polish sources. In the end, this is a movie by a major Polish film director, not some random flick. This stuff generally tends to get reviews and like
