Actor Ice Cube stated on Late Night with Conan O'Brien (1993) that this film was originally intended as an Adam Sandler vehicle.
According to the movie's commentary, Aleisha Allen's (Lindsey) favorite scene was the birthday party scene where her character got up on the stage and sang "R.E.S.P.E.C.T."
When Nick is asked what Suzanne's kids names are, he answers 'Theo and Rudy [Huxtable]' from The Cosby Show (1984).
While Kevin and Lindsay are in the train, Kevin asks his sister if Nick can catch them. She replies, "Maybe 10 years ago". This is a reference to Friday (1995), also starring Ice Cube and Nia Long, in which Cube's character, Craig Jones, can't keep up with Li'l Chris.
(at around 40 mins) Kevin said his mom (Nia Long) thinks Nick is better looking than Taye Diggs. Nia Long and Taye Diggs played love interests in The Best Man.
The bobble head based on Leroy 'Satchel' Paige only speaks to Nick through his conscience, which explains why no one else can hear him.
Ice Cube and Nia Long both starred in another movie together, Boyz N Da Hood (1991)
This reunites Ice Cube and Nia Long for the first time since doing the movie Friday (1995) together.
John Witherspoon was originally set to portray the voice talents of Satchel Paige, but had to drop out at the last minute due to scheduling conflicts. He was later replaced by Tracy Morgan.
Philip Bolden, who plays Ken, interestingly enough at the time, resembled a young Ice Cube, who played Nick.
