The opening scenes of the film featuring Ben Cura and Andrea Deck on a bed share a connection with singer Amy Winehouse and musician Blake Fielder-Civil. The real life couple stayed in the same room where the scenes seen in Creditors (2015) were filmed. This was in Manor House in Osea Island, Essex. Documentary Amy (2015) features footage of the singer and musician spending time together in that same room.
Editor Teresa Font has hidden, in the last ten minutes of the film, a tribute to Jamón, Jamón (1992), a film she also edited, echoing the way she dealt with one particular shot in a scene in which Penélope Cruz faints after being given a ring.
A fully funded Kickstarter campaign, achieving its goal in March 2014, followed a first, unsuccessful attempt at raising funds for the film on the popular crowd-funding website in 2013.
The film was initially meant to be shot on Osea Island, England in its entirety. Considerations about film budgeting relocated the shoot to Madrid, Spain.
