When you write something, at first you might feel very defensive and protective of every single thing, but after a while, you just see what works and what doesn't. Sometimes you do test screenings, and an audience tells you that, or sometimes you eventually just go, 'Let's cut the joke out.'
We were shooting 'Hot Fuzz' in my hometown of Wells, Somerset, and I remember looking at the dailies and going, 'Wait, there's a Starbucks in the shot. I don't remember that being there!' We had to digitally remove it; the same thing happened with a McDonald's in another scene. I had this sensation of, 'What's going on here? Where am I?'
You get some directors, and I can never understand it - there's a thing they call the 'video village' where all the monitors are, and you've probably seen it on set visits - I hate that! I never, ever like sitting in video village. I get either my own monitor or a hand held monitor, and I stand right by the camera.
