The title of this movie, "Cha Cha Real Smooth," is a lyric from the song "Cha Cha Slide" by Willie Perry Jr., better known as DJ Casper. First released in 2000, the song has become a standard at events with group or line dances, such as wedding receptions, school dances, quinceañeras, and bar/bat mitzvahs (which are what this movie's plot centers around).
The age gap between Cooper Raiff and Dakota Johnson is about 7 years.
