I always think it's just best to just make stuff and to carry on making stuff, even if it's not off your own back, because that's the only way... especially as a comedy writer, I make short films and then show them to live audience, so if they're laughing you know you're doing something right.

So many films end up being filmed in London or in the same places over and over again.

'Sightseers' started off as a character comedy double act.

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.

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 both of us [ with Steve Oram], once we decided to do comedy, knew that we would have to come to London to do that.

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