Martin is wearing a Richard Nixon t-shirt during his first trip to the low income housing development. Upon his return to the projects to meet Shawn, Martin is seen entering the building's doorway wearing the same Nixon t-shirt; but when the two boys are shown on the roof of the building, Martin's t-shirt has changed to one of a solid color although he has not changed clothes.
The letter (shown on screen) from the Illinois Housing Development Authority to Tonya Neely contains several mistakes. Those mistakes include the misspelling of Neely (in credits) as Neeley (on the letter); the misspelling of Governor (correct, three times below) as Governer (incorrect once, at the top); repeating the first paragraph, in full, as the third paragraph of the letter; referring to the Illinois Housing Development Authority (header/logo) as the Illinois Department of Housing Development Authority (first time typed, under the first/fictional governor's name); using a fictional governor's name once (Roger Finkin), the first time the governor's name is typed, at the top, and using the then actual governor's name (Rod R. Blagojevich) three other times when typed below, and a fourth time when signed.
Credits for the Neely family are spelled differently. Tonya (Viola Davis) is spelled Neely, Cammie (Serena Reeder) is spelled Neely, and Missy (Marsha Stephanie Blake) is spelled Neeley.
