We always wanted to make a comedy that was a little bit more than that, which had tragic elements to it... that people engaged with - an intelligent comedy essentially.

I think it's very easy to get discouraged early on.

I think what's difficult is proving to people that a script actually does work and sometimes the laughter might not be on the page, it might be between the lines.

Ironically, there isn't much comedy film in Britain, which is quite surprising seeing that we're quite good at it.

The film [Sightseers] is really the story of the journey of a relationship, so the killings are almost a metaphor for the trials they go through. We wanted people to identify with the experience of going on holiday and having a quarrel with your wife, boyfriend, whatever. We knew if we didn't crack that it would not be watchable as a film.

I think 99% of the whole thing is to have passion about the idea yourself. I think part of your job as a filmmaker is to tell someone that might not think it's going to work that, actually, it will work.

Growing up, I didn't feel very cool having come from the Midlands.
