It's nice to think people might be talking about it after they've seen it. With some comedies it's a bit 'wham bam thank you ma'am', and then you just go for a pizza.

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

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.

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

We developed 'Sightseers' as a TV idea but didn't get anywhere with it because all the channels said it was too dark originally as an idea for television.

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

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.

Both of us have forged our careers in London, but a lot of my comedy influences come from my family and my childhood.

When I was a kid the highlight of my week would be doing a fossil hunt at the local quarry... that kind of thing.

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

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.

Manchester has a certain reputation of being cool.

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 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.

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.

If you can make someone believe that you believe in the idea then I think that's worth a lot.

I think in most couples or partnerships, there's a constant struggle for power and dominance.

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