The new opening sequence for spectrum includes nods to Nathan Fillion's short-lived Series Drive (driving a muscle car) and serenity- the "baby barn swallow" scene (The cast escapes by jumping into the hatch of Spectrum as it flies by)
Wray says "They uploaded it to Vimeo, I love Vimeo". This series was released on Vimeo.
During the dream sequence in the beginning Cash is seen wearing a Hawaiian shirt. Hawaiian shirts were a signature costume piece of Alan Tudyk's character Wash from firefly/serenity.
After watching the new opening titles sequence, Wray mentions the dedication to Bruise Camp Bell, saying "He was a great guy. He was a good guy. He was a guy.", A nod to firefly 1.04 shindig & Nathan Fillion's character Mal Reynolds' commentary about Mercy being the mark of a great man, stepping down from pretty good too all right as he stabs his fallen opponent repeatedly.
