While a TV drama, The Shadow Line has a cinematic look, which Blick says “was all to do with the creation of dread.” Blick believes the feeling of “dread” drives audiences to watch a TV programme, explaining: “Why an audience is compelled to join you on a journey is that they are presented with the opportunity that down at the tunnel of the storytelling, right at the end of it there is this dreadful dread waiting and we go on it to see it because it’s delicious to find out what it is.” However, this impending sense of dread is affected by audience’s attachment to the series’ characters. He says: “as we take that journey with the characters, hopefully the audience will invest themselves in the characters. So, by the time the dread comes close, the investment in the character is so considerable that you kind of don’t want to see the dread because of the risk the characters will have to face up to, but of course you do. This lovely duality is what makes you take the journey.”
Blick also shares how to heighten impending dread in a series using filming techniques. He says: “To make people feel dread, you have to put darkness into the frame.” Through darkness, “in terms of story there’s so much obfuscation and disguise, but also just physically it’s kind of frightening, especially if you make them look in the wrong place.”
