From the people who brought you Extreme Fishing with Robson Green, Channel 5, comes Extreme Railways... with Chris Tarrant. Monkey's mind boggles. And then does a loop-the-loop. The new commission was unveiled at the MediaGuardian Edinburgh International Television Festival on Thursday by Channel 5's thin controller, Jeff Ford, and will see the Who Wants to Be a Millionaire? host grappling with timetables in the jungles of Congo, across the Andes and in a desert. No word yet on whether Tazzer will also be recreating the ending to Runaway Train, with a snow-lashed Jon Voight atop the aforementioned unruly locomotive as it hurtles through the Alaskian tundra. But Monkey lives in hope.
