The Killer (Robert Brotherton-Spence)
We casted the killer as someone who looks like Tobias Menzies. This is because he plays the part of Edmure Tully from Game of Thrones and is therefore viewed by people as being feared and strong which are common characteristics in killers. The person playing the role of the killer is tall and has a large structure making him look more like a killer.
The Victim (Connor Garfield)
We casted the victim in our opening title sequence as someone who looks like Stephen Merchant. This is because we wanted the victim to be someone who is quite small in size and stature (excluding Stephen Merchant's height) so that they fit the expectation of the general stereotype of being a victim; being helpless, vulnerable and weak.
