You look at the floor and see the floor. I look at the floor and see molecules.

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.

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

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

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.

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