Iqaluit, NU, Canada
There literally is a "road to nowhere" and we drove out to the end of it in search of Inukshuks and Northern lights. We lost about 10 or 15 minutes of daylight each passing day.
Vancouver, B.C., Canada
We were at Cypress Mountain when they were dropping in hay bales to cover and protect the snow before the Olympics began...
Whistler, B.C., Canada
Ziya and I sang Boom-dee-ah-dah from the peak-to-peak gondola.
Banff, AB, Canada
My singular memory of chasing elk out of the Banff townsite waving a hockey stick was the video showing me running one way (after an elk) and the elk, unseen by me deeper in the forest, running in exactly the opposite direction.
Sudbury ON, Canada
It was here that I expected to meet aliens. Not Sudburians, but creatures generated in my own mind at Michael Persinger's lab.
Boston, U.S.
Here we visited a strange robot that almost seemed conscious. At least when it looked at me.
St. John's, NL, Canada
Is there a better place anywhere in the world than Newfoundland? I wonder.
San Francisco, U.S.
Here for the first time I heard someone define 'consciousness' in a way that I actually understood. And remembered.
Black Rock City, U.S.
Burning Man's theme the year we went? The American Dream. It definitely was dream-like from time to time.
Phoenix, U.S.
This was the site for a conference on consciousness...everyone from physicists to new agers showed up.
Houston, U.S.
No one would claim that Houston is one of the world's great cities, but as a centre for the space business, it is unparalleled.
Pasadena, U.S.
Twice I've waited, and waited, and waited right here for a spacecraft to land on Mars. One of them did.
Panama City, Panama
Our first day here the heat was so oppressive that after Natasha and I stood in the sun for promos, she almost passed out and fell down a hill. I think she'd agree that I saved her. At least that's how I remember it.
London, UK
Daily Planet Goes British...and eats at the finest restaurants.
Gombe, Nairobi National Park (Jane Goodall’s Chimp sanctuary)
(Jane Goodall's Chimp sanctuary) This is the one place I've been where I couldn't believe I was actually there.
Baikonur, Kazakhstan
Where wild camels roam and twisted metal from the age of the space race still stands beside the road.
Mumbai, India
The one and only time I had a TV trailer! We shot on a Bollywood backlot in the afternoon and flew to Toronto in the evening.
Jodhpur, India
Where else can you look out from a fort and see row after row of blue roofs? It was so hot we couldn't shoot between 12 noon and 4:30 p.m.
Agra (Taj Mahal), India
The Taj is definitely over-exposed, but when you're there, no matter how close you get, it's fabulous.
New Delhi, India
Is there anywhere else on earth where you're confronted with sounds, smells and colours like this?
Beijing, China
We spent an entire day at the Summer Palace of the emperor...no messy traffic there.
Shanghai, China
Down on the Bund, crowds surrounded us when we were shooting...some came right up to the camera monitor to check out what "takes" were good.
Kyoto, Japan
The glory of television: I ate dinner in a mall.
Tokyo, Japan
Chaos and order all mashed up into one city.
Aichi, Japan
I'm still waiting for the fantastic "super HD" that I saw there.
Adelaide, Australia
The story told here at the South Australia Museum is familiar: humans arrived, species of large animals disappeared.
Sydney, Australia
I love it when producers think the shot looks best when I'm on the edge of a cliff - as happened near here.
