The title is based upon a quote from William Shakespeare's play "The Merchant of Venice" (Act II, Scene VII): "All that glitters is not gold."
"All That Glitters" reunites (as noted above) Michael Shanks, Dr Daniel Jackson from Stargate SG-1, with Steve Makaj, Colonel Makepeace, also from Stargate SG-1. This makes #6 and #7 Stargate SG-1 alumni to join the cast of Eureka. The others being Teryl Rothery (Dr Frasier), Lexa Doig (Dr Lam), Colin Cunningham (Major Davis), Fulvio Cecere (Colonel Davidson) and Martin Christopher (Major Marks).
At the end of the episode, after a "To be continued..." title card, instead of the usual Eureka closing theme, the "Henry and Beverly" track composed by Bear McCreary is played during the credits.
Some could argue that Eureka wasted an opportunity to exploit Michael Shanks Stargate SG-1 credentials and acting experience in a forgettable part as Christopher Dactylos. An argument could be made that Michael Shanks' wife Lexa had more air-time that he did. Lexa Doig who guest starred as Dr. Carolyn Lam the once estranged daughter of General Landry on Stargate SG-1 has been married to Shanks since 2003. Shanks' wife Lexa appeared in the previous episode of this season.
