The 9-foot-tall "marble me" statue of Awesome in the banana republic of Costa Gravas recalls the Jaynestown (2002) episode of Joss Whedon's series Firefly (2002). Adam Baldwin also starred in this short-lived, but much-loved sci-fi Western, and his character Jayne Cobb unexpectedly discovers a statue of himself while visiting the similarly backwater town of Canton, on Higgin's Moon.
The Russian label on the control room that Sarah photographs while escaping through the basement translates to "Cold War Nuclear Panel".
The Russian on the plaque that causes Chuck to flash reads:
"Fluctuations over the engine
Number 01138
I hate 7165
John Bush 8157
Separation Test System
Yaakov Smirnoff, Russia"
Todd Sherry, who plays Dr Fred, also had several appearances in The O.C. (2003), another show created by Josh Schwartz.
