"Along with Airplane, An American Werewolf in London, and Raising Arizona, this film is one that I can silently mouth along with every single line of. I don’t know if Reiner, Guest, McKean, and Shearer could have ever known back in 1984 quite how far-reaching the influence of this movie would be. As a British director who made his start in TV comedy, I can vouch for the fact that this film is one of the key texts for every single UK comedy writer, actor, and director of my generation. The fact that it was performed by American actors doing killer English accents just makes that all the more impressive and ironic. So I cannot overestimate its position as an unassailable comedy classic. Along with Monty Python’s Life of Brian (also on Criterion) and Mike Leigh’s 1976 TV movie Nuts in May, it really became one of those movies that create strong bonds in creative partnerships. You either liked Spinal Tap or you were not worth talking to; it became that simple. And quite right too. It’s eighty-four minutes of comedy heaven."

"With the compilation albums, I am cheating. It meant I didn't know which album to choose. I sometimes DJ. When I DJ, I use a system to take people into an ecstatic trance through music. I might start with Brian Eno and some ambient music and then move to other genres. I might use classical music or Indian music. But, invariably, when I get to the third rhythm of trance and when I really want to take people into that state, I am almost forced to go to Underworld again and again. Underworld brought together song and dance in a way that I have not heard anyone match. The Chemical Brothers are great and New Order are obviously great, but Underworld take me to a tribal edge that is so ferocious and yet, simultaneously, so intelligent. 'Rez' is one of my favourite songs – even though that is not one of their most tribal. 'Moaner' and 'Born Slippy' are their more tribal tunes. I find their textures and landscapes and vocals – which don't get in the way and help you lose yourself when you are dancing – make Underworld difficult to surpass. I was so proud of them when they got to do the Olympics in 2012. I felt that was their due. I contacted them before the Olympics and had a lovely communication with them. I told them that I thought they were the most revolutionary and iconoclastic band of the last 20 years. Then, about a year later, Danny Boyle used them during the opening ceremony. I saw them play recently at the Hollywood Bowl and I danced so much that I badly twisted my ankle and couldn't walk for about two weeks. It was still worth it. Dancing injuries are to be worn like medals of honour."
