 In the episode's original plot, the bank robber was to have jumped into Mulder's body. There was, however, a belief at the time that neither Scully nor Mulder should directly experience such phenomena. After Fox and the studio argued against the idea of using Mulder in such a way, the producers agreed to make the change. The opening bank robbery scene was filmed on location in Vancouver, where Jason Schombing's acting led some bystanders to believe that robbery was a real one.
