Co-showrunner Robert Singer says thanks to the show being a "very well-oiled machine," the show was able to proceed without any problems, filming nine days for each episode instead of the usual eight. Stars Jared Padalecki and Jensen Ackles say they felt a responsibility to avoid being reckless off-set in Vancouver. “It would have been shutting down production and putting people out of work again, so everybody was more careful than they were required," says Padalecki. “We all felt the importance. We weren’t going out on weekends.” Ackles added: “Everybody was taking it very seriously."
