Baldvin has described Black Sands as less of a murder mystery, more rather a "Dark, romantic thriller... that happens to include a murder."
Despite filming during lockdown heavy COVID-restrictions, filming wrapped with zero cases of infection.
Actors Ævar Þór (Gústi) and Anna Gunndís (Steffí) were long time friends prior to filming. Their on-screen counterparts have been married for 12 years, almost identical to the actors' friendship history.
A key theme in the series, according to director Baldvin Z, is 'nature vs. nurture.'
Every single pop song in the series' soundtrack is deliberately chosen and are hidden messages often found in the lyrics.
