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 accept sceptics, you've got to have challenges.

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

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

I'd make a bad preacher.

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

Can't get around the old minimum wage, Mortimer.
