In the original Cube
- Doing It for the Art: The effects studio for the film worked on it only to show support for Toronto's film industry, and at no cost.
- 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.
- No Budget: The original was produced for only $400K. Only one set was built and all of the CG was done for free as a Doing It for the Art moment (as mentioned above).
- Serendipity Writes the Plot: The movie came about due to something like this:
"We only have money for one set, one room.""That one room could represent a bunch of rooms that look identical.""Well, a bunch of identical rooms would be a maze.""So, why does this maze exist? Why are our characters trapped in it?""I think that's the plot."
