Production
Through Night and Day was directed by Veronica Velasco and written by Noreen Capili. Lead actress de Rossi was supposed to direct and write the script for the film. De Rossi had a "complete story" for the film but due to pressures on fulfilling the lead actress role for the film, she entrusted Noreen Capili to complete the script and decided to direct the film instead. The final script was said by de Rossi to be "100 times better" than what she could have did. De Rossi personally went to Iceland in June 2018 to develop the story for the film and it was snowing heavily during her stay in the country. Her acting commitment with Since I Found You also held her back from working on the film's story and only managed to create ten sequences before handing over the writing role to Capili. De Rossi dropped plans on being the film's director. If the plan pushed through Through Night and Day would have marked de Rossi's directoral debut. Veronica Velasco selected to direct the film. Velasco gave the leads, Paolo Contis and de Rossi creative freedom in delivering their lines and did not oblige them to strictly follow the script. A significant part of Through Night and Day was filmed in Iceland with principal photography done in the country within a span of nine days. In an accident scene, the temperature went down at around in the filming location. An entire day was also wasted due to unforeseen heavy rainfall. Seven days were spent by the crew touring around country through the Ring Road. Iceland is also de Rossi's "dream destination" which is also associated with pop singer and her idol Björk. The title for the film, Through Night and Day was derived from the lyrics of Eric Clapton's "Tears in Heaven".
Music
's "Tears in Heaven" was supposed to be the theme song for Through Night and Day. The record label for the song allowed the work to be used for the film but Clapton himself did not give consent due to the song being "very personal" for him.
