Other mistake: After Ken shoots the pregnant lady, she rolls her head to the side, apparently to indicate death, but her stomach movement shows she is still breathing. (00:01:46)
Other mistake: After seeing Joe Montana play in Super Bowl XIX, young Kurt said, "I knew I wanted to be that guy." When he goes outside to pass the football, young Kurt has "Warner 13" on the back of his jersey - not Montana's #16 but the #13 that he could not know in advance that he would eventually wear during most of his adult career. (Jersey numbers are not necessarily that available for a player to have his pick). (00:02:02 - 00:02:33)
Suggested correction: This is trivia at best, certainly not a mistake. While it's true he wore #12 in high school, there's no reason he couldn't have liked #13 as a child. And, many key position players do get to pick their number, from the available range, which Kurt certainly did.
Other mistake: Mike said, "I don't feel too good [sick from drinking Mexico's "dirty water"]." Rafo responded, "Run! It's gonna come out" and Mike walked into the weeds. Mike apparently "forgot" about his impending diarrhea because he was able to run up to the road behind Rafo when their car was being stolen. (00:41:59 - 00:44:00)
Other mistake: William Tillich (AKA Bill Tell) had one suitcase which could not possibly hold enough sheets (or thin blankets) to cover/wrap all the furniture in his motel room like he did. (His suitcase was not very large and also contained his clothes.) He covered an even larger area of furniture in Gordo's house. It isn't clear if he used his own sheets or just happened to find the same kind in Gordo's house.
Other mistake: Tom told David and Lily, "Whoever murdered that girl [Jessica] didn't have sex with her. They used a corn cob." The crime scene photo of the "corn cob" actually showed a partially opened "husk of corn" or "ear of corn." The "cob" is the inner part of the ear beneath the kernels of corn and could more realistically be used to "assault" someone. (00:33:30 - 00:38:30)
Other mistake: A vehicle bought at a NYPD auction must be paid for in cash, including tax. Ballena won the auction with his $60,000 bid for the Navigator, but it did not appear that Ballena was carrying that amount of cash on him. (He was not carrying a bag or briefcase.) If Ballena did have the $60,000 plus tax in cash, it would have taken some time for it to be counted before the paperwork could be completed, but no money was shown during the process. (01:05:03)
Other mistake: Packie arrived at Frank's garage on a bicycle, wearing a brown coat, hat, gray hooded sweatshirt, patterned shirt, and a T-shirt. Swaino arrived on a motorcycle, wearing a tight jacket, no hat, black gloves, and black jogging jacket with white trim. When they were outside by the grill, they had large sweaters over their coats. It isn't known where these sweaters came from. It can be assumed the blanket Swaino used at first was from Frank's garage, but the sweaters did not appear to be Frank's. (00:25:32 - 00:37:35)
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.
