Folks have to pin me down because, for one thing, I don't have a laptop. I don't have an iPhone, and I refuse to carry them because they're immensely hackable.

My great-grandfather, Sam Aykroyd, was a dentist in Kingston, Ontario, and he was also an Edwardian spiritualist researcher who was very interested in what was going on in the invisible world, the survival of the consciousness, precipitated paintings, mediumship, and trans-channeling.

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 get offers all the time from film makers, but they are unknown quantities. I don't go there and do experiments.

My parents never had any money. It was cash flow. It flows, and you got your fingers in it for a little while, and it flows away. That's all I know about money. And I don't know, it flows and it's a river, but you can never, ever keep it. As an artist, I can't keep it. But hey, a man who dies with a cent in the bank is a foolish man. So I guess I'm going against the conservators. I'm a spendthrift.

One minute you're up half a million in soybeans and the next, boom, your kids don't go to college and they've repossessed your Bentley.

Certainly the format of ghostbusting lends itself to a videogame beautifully.
