Because of budget constraints, the production crew will often recycle sets to save money. For instance, the hospital corridor for Smallville Medical Center was transformed into Lex's cell in "Asylum", which was later transformed into the asylum corridor, before finally being morphed into Dr. Teng's laboratory in later episodes. When the production crew could not afford to rent a local night club, with all of the extras they needed, for more than one night they decided to film all of the wide shots—capturing the three hundred plus extras—on the first night. Then, with their remaining funds, they filmed close-ups of the actors with a limit of fifty extras in the background. When scenes in the season three premiere called for Lex to be stranded on a deserted island, instead of traveling to a beach, the crew found a mountain range in Vancouver that had an area in front of the mountain that resembled a beach. The resemblance was close enough that all they needed to do was to bring in some palm trees to complete the aesthetic they were going for. All of the island scenes were shot in one day.
