Character mistake: There is a misspelling on the cover of the issue of Forbes magazine shown in the presentation about Stark's life. It reads "Tony Stark takes reigns at 21". The correct spelling of the word is "reins". Stark may "reign" at Stark Industries but he would take over the "reins" of the company.
Character mistake: The information on Walter's "patient information sheet" lists his address as 5962 Delco St but numerous shots indicate his house number is 238. (01:03:25)
Character mistake: Throughout the movie the character Andrea's name is consistently mispronounced. When her husband Chris shows up at her office to apologize for looking at her bank statements and offer to take her to lunch, he approaches the receptionist saying he's looking for his wife whine he calls Andrea (pronounced like Ann-drea) but then in the same scene he calls her Andrea (pronounced Ahn-dre-uh) I understand maybe another character mispronouncing her name but not her own husband.
Character mistake: During the Nativity play, Pastor Phil says, "Are we ready to see the result of the Immaculate Conception?" The term 'Immaculate Conception' refers to the conception of the Virgin Mary (conceived without Original Sin), not to the conception of Jesus. Furthermore, the Immaculate Conception is a dogma of the Catholic Church, and not something which a Protestant pastor like Phil would believe in.
Character mistake: McQuarry enters the subway at the 103rd Street station on the 1. He is transferring to the 2/3 at Chambers Street when Bose approaches him. However, it makes no sense to transfer here. As someone who knows New York, McQuarry would transfer to the 2/3 at 96th Street to benefit from the express ride to Chambers. (01:03:05)
Character mistake: When Leon goes to see Susan Hoff with his photography portfolio she tells him he needs improvement. After she leaves, Leon tells Jurgis that he thinks she hated his work and Jurgis tells Leon "when she hates somebody's work she gives them about a minute, you got three." In reality, she actually did give him one minute almost to the second. (00:06:58)
Character mistake: At the rehearsal dinner, when Steve walks up to Miranda she calls Steve "Dave." Dave is his real name.
Character mistake: When Alex Stillman is facing Karen 'Razor' Jones for the second time in the film he calls her All-In with Pocket Queen's in his hand whilst she has AJ of Spades whilst the cards on the table are: Ten of Spades, Jack of Hearts, 2 of Spades and the King of Diamonds. However the commentator then states that either a spade, Jack or Ace will cripple Alex but that is not the case as an Ace would give him a Straight and she would only have 2 pair Jacks and Aces.
Character mistake: After Father Flynn has completed his first sermon, Donald Miller comes into the dressing room and says "That was some sermon, Father." Flynn then says "Hi Jim". Jim is the name of the other altar boy. He should have said Donald.
