Jail scenes were shot at an active juvenile hall in Martinez, California.
Swamp scenes were filmed at Lake Herman, just a few paces away from the site of the Zodiac Killer's first murder, in Benecia, CA.
The actors who played Robert Nielsen and the convenience store clerk in the robbery are both natives of Buffalo, New York. They attended neighboring Catholic high schools (St. Joseph's Collegiate Institute and Nardin Academy, respectively).
The actor who played the tower guard, who shot at the fugitives during the breakout scene, was also the real security manager and RV driver on the set of the episode.
