I live in a high rise with my family part of the year in New York and I don't know three quarters of the people in the building. We live in the same square-footage and I wouldn't know who they were.

Parodies of commercials are by no means new and have been popular going back to black-and-white TV shows of the '50s.

The entertainment business is not the be-all and end-all for me.

I like really good movies, but I can enjoy a really bad movie, too.

We have the most beautiful planet - the Rockies, the purple fields of the United States, the Lake District, the Pyrenees, the turquoise seas of the tropics.

One of my symptoms included my obsession with ghosts and law enforcement - I carry around a police badge with me, for example. I became obsessed by Hans Holzer, the greatest ghost hunter ever. That's when the idea of my film Ghostbusters was born.

I've always been a big fan of science fiction and of the worlds of the spiritual and the mystic.
