Cube/Trivia

In the original Cube

 * Hey Its That Guy: David Hewlett (whom you might know better as Rodney McKay), and he's still an Insufferable Genius, to boot. There's also Ezri Dax.
 * Canadian viewers may recognize Rennes (Wayne Robson) as Mike Hamar, the ex-con from The Red Green Show.
 * The Danza: David Hewlett as David Worth. This might be chalked down to coincidence if not for the fact that Hewlett and Natali have been good friends since high school - because of this he probably had some imput in choosing his character's full name.

In Cube 2: Hypercube

 * Hey Its That Guy: Nick Knight
