Actor Allusion: One happened accidentally to Claude Rains when he was taking his daughter to see this movie during cold weather. He was heavily covered and when he asked for tickets, the attendant immediately recognized him.
What Could Have Been: Boris Karloff was the original choice to play Griffin, but decided not to take the role because his real face would only be seen for a few moments(when Griffin dies), but also because Universal president Karl Laemmle wanted him to take a pay cut.
Actor Allusion: In "Exposed," Darien opens an SWRB cell door expecting to free Hobbes and Alex, but instead frees a man that seems familiar to him. The man is played by Adam Storke, who co-starred with Vincent Ventresca on the short-lived series, Prey. To play up this moment, before the first airing of "Exposed," the Sci-Fi Channel aired the series finale of Prey, which ended with Storke's character (Tom Daniels) being locked in an actual cell. It is left to the viewer to decide if Storke is actually reprising (however briefly) his old role or not, however.
Chinese agent Chen Po Li in "The Invisible Woman" demonstrates martial arts skills, which he credits to Walker, Texas Ranger, which actor François Chau appeared in a few episodes of.
In "Perchance to Dream" and "Going Postal," Darien and Hobbes' antics are likened to The Three Stooges. Paul Ben-Victor played Moe Howard in a 2000 biopic.
Keep Circulating the Tapes: Season 1 found its way to DVD in 2008. Season 2? Not so much, but it's at least on Hulu along with Season 1.
Screwed by the Network: The series was a rating success on Friday nights, but a move to Mondays for Season 2 saw a decline. Though the move was reversed, ratings never fully recovered.
What Could Have Been: In "The New Stuff", the Agency learns of Chrysalis' plot through a tabloid. Production staff had planned for the tabloid to be The Chronicle as a Shout-Out, but they never heard one way or another from the network about doing it.
