 One major issue faced by the cast and crew, during the three week period that exterior scenes required to be filmed over, was a severe drought taking place during work, restricting cast members to having showers within two-minutes.The heat at the location also led to one member, Tosin Cole, developing heatstroke during the work and requiring treatment.The interior scenes – including those involving Art Malik’s character Ilin – were primarily filmed back in the United Kingdom once the cast had finished in South Africa, at Cardiff’s Roath Lock Studios.
