I'm a big collector of vinyl - I have a record room in my house - and I've always had a huge soundtrack album collection. So what I do as I'm writing a movie is go through all those songs trying to find good songs for fights or good pieces of music to layer into the film.

The scarcity of the music not only makes the music itself enjoyable but it also gives the collector a strange sense of superiority.

It has been common knowledge to informed collectors that many times the finest and rarest art glass is found unsigned.

I'm a geeky toy collector and to have toys of your own characters is unbelievably cool.

A saboteur in the house of art and a comedienne in the house of art theory Lawler has spent three decades documenting the secret life of art. Functioning as a kind of one-woman CSI unit she has photographed pictures and objects in collectors' homes in galleries on the walls of auction houses and off the walls in museum storage.

Megacollectors suppose they can enter art history by spending astronomical amounts.
