Did you set out to make a comedy first and foremost, or were the film’s darker elements in place from the start?
Alice Lowe: We wanted to take the stereotype of British tourism, which has this extremely polite veneer, and do something that confounded that. But we didn’t want to make a light, Carry On-style murder comedy – we wanted it to have some psychological veracity, and to challenge people. We knew the characters had to have realistic psychologies for you to be willing to go with them on their journey. The whole movie is essentially about two damaged people coming together, triggering something in one another and becoming more than the sum of their parts.
Did you look to any real serial killers for inspiration when developing the characters?
Steve Oram: We did loads of research, and found out stuff like the fact that Fred West did DIY for his neighbours. People liked him on the street, which is astonishing when you think of what he did. But one of the recurring traits in serial killers is that they’re basically really into themselves. They’re very “me” people! They think they’re playing God, but they’re just making up the rules as they go along. Chris has his own morality, but it’s total bullshit.
AL: Tina is actually much more creative as a killer, she genuinely wants chaos. That totally fucks with Chris’s world view, but also adds an element of excitement. He decides he would rather have a partner in crime that loves him, than be alone.
