Javier Ambrossi and Javier Calvo initially didn't want to direct this film and tried to get other directors to direct it. The phrase "Lo hacemos y ya vemos", which is said in the play, was what motivated the duo to write and direct the movie themselves.
Javier Ambrossi and Javier Calvo, the writers and directors of the movie, also authored the musical on which it is based.
The two directors showed this film to famous Spanish director Pedro Almodóvar, who praised its casting of its main protagonists.
This film is based on a theatre play created by the same directors and it has been a success around Spanish theaters since 2013.
Its directors, Javier Calvo and Javier Ambrossi, were drama teachers on a popular Spanish talent show called "Operación Triunfo". In fact, two of the actresses who perform on the theatre play this movie is based on are ex-contestants of that show (Marta Sango and Nerea Rodríguez).
