A quote from Nick, "I don't know karate, but I know ka-razay!" when he's confronting Chuck, are actually lyrics from James Brown's 1974 single "The Payback" from the album of the same name.
Ice Cube was approached to do another sequel, but declined, saying that he wanted to go in a different direction. He then proposed that the movie idea be turned into a TV show, which it did: Are We There Yet? (2010).
Shipped to theaters under the name "Needs Work"
This was actually the 4th movie with Ice Cube and Nia Long, the 1st movie was Boyz in the Hood, 2nd being Friday and thirdly Are We There Yet.
When Nick tells Chuck, who is played by John C. McGinley, that he feels good sitting on a private toilet, Chuck says, "Feeling good is good enough." That line is said by Willem Dafoe in the 1986 Oscar winner Platoon, which stars McGinley.
