Rafael Azcona died in 2008 and David Trueba is brother of Fernando Trueba, the director of both films and also is brother-in-law of Cristina Huete, producer of both films and also producer of five films directed by him, David Trueba. David Trueba said : " I like to receive credit in the films I worked, but not in the films I did nothing. As author of the first film I have nothing to claim in the second one"
Mandy Patinkin and Cary Elwes previously started together in The Princess Bride (1987) as Inigo Montoya and Westley, respectively.
The movie was announced in 2012, when Fernando Trueba and Penélope Cruz happened to present two different movies at the San Sebastian Film Festival. They got together for dinner, where both started to talk about the making of La niña de tus ojos (1998), how fun it was, and really contemplated the idea of doing a sequel.
