 Smallville's Main Street was filmed in both the town of Merritt, which is three hours east of Vancouver, and in the town of Cloverdale.Most of the filming took place in Cloverdale, since the town had a long stretch of vacant buildings that could double as Smallville's Main Street.When the production crew came to film the opening teaser, they had to decorate the town with ribbons and balloons, as well as paint some of the buildings to attain Millar's idea of "Smalltown, USA".
