My whole thing is to entertain, make people laugh and to forget about the real world for awhile.

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 grew up on the edge of a national park in Canada - timberwolves, creeks, snow drifts.

Personally, I liked working for the university. They gave us money and facilities. We didn't have to produce anything. You've never been out of college. You don't know what it's like out there! I've worked in the private sector ... they expect results!

My first jobs were all civil service. At 14, I worked for the Canadian National Railways. At 16, I worked for the Canadian Penitentiary Service.

I believe that if a man dies with a single penny still sitting in the bank, he's a fool.

Am I a trance medium? No. Have I got a gift psychically? Absolutely not. But I believe in the survival of consciousness after death.
