The iconic hose scene was shot twice. The first one wasn't useful because the pressure was so big that Carmen Maura fell down. While the crew adjusted the hose, Maura dried herself and changed the dress. The second time the scene was shot perfectly, but Maura had to dub herself because of the water noise.
In the scene where Tina (Carmen Maura) washes dishes in Pablo's (Eusebio Poncela) kitchen, she wears an apron that has the logo for What Have I Done to Deserve This? (1984). The logo is the same one as the one used for the Spanish posters for that film.
