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

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

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

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.

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.
