Continuity mistake: Backstage of the Versace show. The young designer asks Maurizio what's his name as he sips some champagne. He holds the flute glass in a different way between shots. (01:09:20)
Factual error: Backstage at Versace's in 1983, in the scene with the enigmatic "Walter" the song from Eric B. And Rakim, "Paid In Full" plays diegetically. The song was a 1987 release. (01:09:05)
Continuity mistake: At the beginning of the scene when Patrizia finds her maid's counterfeit Gucci, she puts her shopping bags on the kitchen counter. They are all roughly parallel, but when she questions Ira, the Burberry shopping bag is perpendicular to the others. (01:05:20)
Continuity mistake: When Maurizio discusses Rodolfo's inheritance and the taxes to pay, look at the objects in front of Patrizia; they go from the side of the book, to the top of it. (01:01:45)
Factual error: When Patrizia gives her reluctant father-in-law the locket the birthdate of the baby is not only historically inaccurate (real life Alessandra Gucci was born in 1977, in the movie they hadn't even met by that time) but does not fit the altered timeline of the movie itself, since it says January 20th 1980. It was established that they met in 1978 and married 2 years after that, so a baby in early 1980 is way too soon considering the pregnancy happens way after the wedding in the movie too. (00:58:40)
Continuity mistake: Patrizia is trying on some shoes inside the store in Via Condotti after Sophia Loren left. Al Pacino checks her out from behind, and you can see that there's nothing directly in front of the stool, but in close-up there's a pair of red heels. (00:42:00)
Continuity mistake: When Patrizia calls the fortune-teller, the ice cream cups change position on the table between shots (when she says ""Will I get what I want?"). (00:40:50)
Other mistake: When Patrizia watches Pina Auriemma's commercial, the word "verità " ('truth') is written twice wrong (no accent), and most importantly, the phone number is a 800 number, which was not a valid number in Italy back then, being a modern (post-1999) prefix for toll-free services. In the 80s, TV fortune reading services as the one the movie wants to portray would have a normal area code. (00:40:00)
Continuity mistake: Paolo is lamenting his father's lack of trust in his 'brilliant ideas'. There's a shot on a befuddled Lady Gaga staring in space while Paolo in his farcical accent says "because-ah." Jared Leto's arm is in frame, and it's immoble. The shot was edited in from a different take of a different part of the scene, because at that point Paolo is supposed to be gesticulating like a buffoon. (00:36:50)
Other mistake: When Al Pacino reads the magazine (Grazia) with the news of Maurizio's wedding, the article is probably a reproduction (with the actors' picture in place of the actual Maurizio and Patrizia) of a news story about the actual wedding, so the details conflict entirely with the fabricated story. You can easily read (in Italian of course) that they met in 1971 (1978 in this movie), there are over 500 guests to the wedding (much more of a private affair here) and Maurizio had to ask some of his friends to introduce Patrizia to him and asked her out, which is the opposite of what happens here. (00:28:40)
Continuity mistake: The wedding scene has a POV from Patrizia's perspective as she walks down the aisle. She passes by a cute girl with braids, goes well past her, but in the reverse angle that follows she is in front of her still and says hi. (00:26:20)
Continuity mistake: When Rodolfo tells his son to do whatever with Patrizia but "No, not marry", the handkerchief disappears from his hand in the reverse shot. (00:20:05)
Audio problem: Rodolfo is watching the old movie reel after lunch with Patrizia. He greets his song saying "Ah, Maurizio", but his mouth does not move. (00:18:15)
Continuity mistake: Look at the level of the wine in Maurizio and Patrizia's glasses when Rodolfo during their lunch date mentions the saddest moment of his life. The glasses are fuller when Patrizia takes his hand a few seconds later. (00:17:15)
Continuity mistake: Rodolfo during lunch tells the story of how young Maurizio who brought a moment of levity to his wife's funeral. When the camera is behind Jeremy Irons' head, the cigarette smoke signals that the hand out of frame is raised. In the shot from the side of the table, the cigarette is on the table, and you can see the smoke disperse before it reaches the level of the other shots. (00:17:10)
Factual error: The scene inside the bookstore takes place in March 1978, as shown also by the calendar behind Adam Driver, which says "March 1978." But, it's not a March 1978 calendar. The Sundays (marked in red) don't match. They just took whatever calendar they had and changed the top. (00:09:40)
Continuity mistake: Patrizia says the kinda dumb line about being bored by reading. Adam Driver looks a little on the dejected side, holding two books in hand. At the cut when she asks him what are those books about, the books are tilted in the opposite direction. (00:09:20)
Factual error: When Maurizio notices Patrizia peeking at him from behind the law book, you get a look at the bottom shelves of the store. A large book bears the title "Come funziona la psicologia", Italian version of a Jo Hemmings book from 2019. The scene is set in 1978. (00:08:30)
Factual error: The name of the truck company owned by Patrizia's stepfather is "Corriere F. Reggiani." It's not a fitting name for his company, since we see the company fleet is made of flatbed trucks, and "corriere" in Italy is the express delivery courier. Later in the movie there's a movie prop that accidentally shows on screen an article about the real life story, and the name of the company is "Autotrasporti F.Reggiani", which would be the correct, and actual, name.
Factual error: In the opening view of the lunch where Maurizio's father meets Patrizia and is less than impressed by her, an elderly lady is reading a newspaper. On the newspaper there' s the ad for "Il profumo del potere", which is the Italian version of TV miniseries/soap "Bare essence", judging from the photo the two-part, 4-hour version. It came out in Italy in December 1983, and the scene is set in the late '70s. (00:15:15)
Answer: No.
