I'd make a bad preacher.

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.

Everyone fears the cut of the blade. It doesn't matter after that. I know the spirit survives as there is so much evidence of the survival of the personality in the afterlife.

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.

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.

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

The reason I'm here today, the reason I own a brand new Harley-Davidson motorcycle and the reason I have a big log cabin and I got cars and all kinds of stuff is because I'm a writer and writers own everything. So you learn how to write.
