Smallville was primarily filmed in and around Vancouver, British Columbia, Canada. Key filming locations included:

• Vancouver and its surrounding areas, which stood in for the fictional town of Smallville and Metropolis.
• The Kent Family Farm scenes were filmed at a real working farm in Aldergrove, British Columbia.
• Smallville High exterior shots were filmed at Vancouver Technical Secondary School, and interior shots took place at Templeton Secondary School.
• The exterior of Lex Luthor's mansion was filmed at Hatley Castle in Victoria, British Columbia.
• Downtown Smallville scenes were filmed in Cloverdale, a community near Vancouver.
• The coffeehouse known as The Talon was filmed using the Clova Cinema in Cloverdale.

These British Columbia locations were chosen for their ability to mimic the Midwestern American setting of the show while providing beautiful and versatile backdrops.
