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 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: 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 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: 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)
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 Pacino introduces the country workers to "My nephew Maurizio" his sunglasses suddenly jump from his head to his hand. Adam Driver in this second shot affectionately touches his wife's back, and the gesture is repeated in the next angle change. (00:44:20)
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: 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)
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: 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)
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)
Factual error: At the Versace fashion show set in 1983, the photographers are using cameras with modern flashes installed, complete with LCD displays. (01:08:55)
Factual error: In the audience of the Versace show in 1983, there's a shot in the crowd showing someone portraying Karl Lagerfeld, in company of his iconic cat. Lagerfeld wasn't known for carrying felines around during that part of his career. (01:09:00)
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: 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: 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)
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)
Continuity mistake: When Patrizia is told by Domenico "You have a natural advantage, you are not a Gucci", her hands are down and separated, and then immediately in the next shot up and joined. (01:11:35)
Revealing mistake: When Paolo tells Patrizia "I do have something on my father", you can plainly see the separation between the frowned forehead of Jared Leto and his "bald cap" prosthetics. (01:15:30)
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.
