When Preston is getting his Chromeskull tattoo on his chest, it is actually a shot of Nick Principe (who plays Chromeskull) receiving the tattoo for real on his back.
Johnathon Schaech, Agent Sells, was also in the original Laid to Rest as Johnny.
The character 'Trost' is named for cinematographer Brandon Trost.
Brian Austin Green (Preston) and Thomas Decker (Tommy) starred in Terminator the Sarah Conner Chronicles, while Owen Yeoman (King) had a prominent role in the pilot episode of that show.
