Like the number "Come What May", the mashup of the songs "Diamonds Are a Girl's Best Friend" and "Material Girl" also comes from movie Moulin Rouge (2001) starring Ewan McGregor and Nicole Kidman. On the soundtrack from the film, the mashup was given the title "Sparkling Diamonds".
Whilst shooting "Footloose" Becca Tobin (Kitty) sustained many bruises from Chord Overstreet (Sam).
The song "Unchained Melody" was featured in the 1990 film Ghost (1990) for which Whoopi Goldberg won the Best Actress in a Supporting Role Oscar during the ceremony held in 1991. In Glee, Ms. Goldberg plays Madam Carmen Tibideaux from NYADA.
The songs in the mash ups that the girls sing are from Moulin Rouge which stars Nicole Kidman. The songs that the guys sing are mash ups from movies with Tom Cruise who was married to Nicole Kidman for 10 years.
