Continuity mistake: Rodolfo verbally eviscerates Paolo who presented him his sketches. Then he adds "Oh no, forgive me." As he does that, his eyeglasses switch hands. (00:55:50)
Continuity mistake: Aldo is having lunch with Maurizio and Patrizia at the country house. He says "I love this place", cigar in hand. Puts the hand down, but the hand is up in the following shot. (00:45:05)
Continuity mistake: When Paolo shrugs at his father sniping at his fashion taste saying "Ehh, it's chic", his arm is lowered in one shot, up in the next. (00:36:00)
Continuity mistake: Aldo after the birthday toast tells Patrizia that the Gucci were saddle-makers. His son in the wide angle claps his hands together, nothing in them. Closer angle, and he conjured smokes and a lighter. (00:35:25)
Continuity mistake: When Aldo invites Maurizio to play a heated game of calcio fiorentino at the villa, the people lounging in the background change position between shots. (00:34:20)
Factual error: During Aldo's phone call to the newlyweds, above the washing machine there's a bottle of "Omino Bianco" laundry detergent. It's an Italian brand that in the 80s was exclusively an additive bleach in powder form, the one in the movie is the modern liquid detergent version. (00:33:30)
Character mistake: Aldo tells Rodolfo to reconcile with his son, saying "Sunday is my birthday." Aldo Gucci was born on May 26th, which was not a Sunday in 1980 nor 1981, which is when the scene would take place. (00:31:30)
Factual error: Rodolfo's brother Aldo has a real knack for business, since he comes with a business proposition to sell Gucci products at the Gotemba Mall in Japan in 1980, when the mall opened in the year 2000. (00:29:50)
Factual error: During the wedding scene and in other rare moments Lady Gaga and Adam Driver speak actual Italian (let's not get into the logic of the fact that they speak throughout the whole movie with 'English with Italian accent' in Italy, especially when it is pure pantomime like Leto's), but they are not native speakers, their pronunciation is off. Al Pacino does worse when in the next scene he greets the housemaid Claudia with "Buonasera" (good evening) which the captions (and the rest of the dialogue, since he repeats the line in Englishalian too) translate as "Good Morning."
Revealing mistake: When Maurizio has a water fight with one of the truck drivers, above the logo of the fictitious company "Corriere F. Reggiani" on the window of the truck you can see the logo of "F.lli Zucchetto", (Zucchetto Brothers) the real company owning the truck, who organizes real life gatherings of vintage truck owners. (00:22:50)
Continuity mistake: Patrizia is having lunch with her future father-in-law at the historic Terrazza Gallia restaurant in Milan. She jumps nervously when he first addresses her; during this transition, the waiter who just tilted the bottle up is still pouring with the bottle tilted down in the second shot, and a waiter that was taking care of the table behind Lady Gaga disappears. (00:15:15)
Factual error: Adam Driver and Lady Gaga are eating some street food in Piazza del Duomo in Milan after trying the expensive and historic Savini restaurant. The scene begins with in frame the sign of the jewelry store Currado, a brand established in the 90s and that opened that particular store in 2007. (00:12:00)
Factual error: When Patrizia is stalking Maurizio pretending to read some law book from the university, she's leaning against a shelf that sports a grey book by the title "Formazione; I metodi." On the book, you can see the logo of the publisher, Raffaello Cortina Editore, founded in 1980. The scene is set in 1978 (the book is from 2014, incidentally, and the scene was shot at the Cortina bookstore). Another even more obviously anachronistic book is next to Maurizio on the lower shelf; about the regulations of the European Union, which didn't exist at the time. (00:08:25)
Factual error: The climax of the first show by Tom Ford happens with the bold presentation of a Gucci g-string. Maurizio is alive and well here, but the event happened at the presentation of the Spring collection in 1997, months after his death.
Continuity mistake: Paola tells Patrizia that she made strudel. Her cigarette hand is down, but in the next shot the arm is on top of the bench's back. (01:42:05)
Factual error: Maurizio Gucci is killed practically in front of a recognizable landmark (Fontana delle Rane, "Frog Fountain") in Rome, but in reality he was killed in Milan. The registration plates of the cars in the scene are also "MI", which would be a pretty extraordinary coincidence in Rome.
Continuity mistake: In the Christmas gifts scene, Lady Gaga picks the gift card with her left hand, it's in her right hand in the next shot, left hand again at the cut. (01:41:20)
Factual error: When Patrizia tells Maurizio that she talked to Paolo, the coffee table showcases a variety of books completely inappropriate for the 1983 timeframe (for instance there's "All Prints of Kusama Yayoi" with her pumpkin print from 2005 on the cover and "The Lives of Others" by Simon Watson, which came out in 2020). (01:16:45)
Revealing mistake: Maurizio tosses on the table the newspaper with the article about the new "P.G." brand launched by his cousin Paolo. The article itself is a copy/paste of the same paragraphs repeating a bit of history of the Gucci family and brand. (01:11:05)
Factual error: When Maurizio is discussing for the first time Paolo's burgeoning business, on the table you can see San Pellegrino bottled water with the modern format and packaging instead of the appropriate bottle shape and label for 1983 that appears in other scenes. (01:11:00)
Answer: Yes. Basically, within the narrative of the film, Maurizio is weak-willed and easily manipulated by Patrizia; he didn't even want to be involved in running Gucci in the first place and has no real business acumen. So, he both overextends the firm and spends a huge amount of money on an extravagant lifestyle, which leaves him in financial trouble and at the mercy of a hostile takeover.
