Thanks to BB and everyone here for noticing the chart. I agree there is indeed tons of stuff that I didn't get in, due largely to my own ignorance and ability to work on a deadline. But I can't help myself in explaining 2 items:

Vin Diesel is included because he's a self-avowed (-confessed?) D&Der. His connection to Asimov is that "Pitch Black" was based loosely on Asimov's story "Nightfall."

And there is a Star Trek ref! "The Enemy Within" which connects to Cons of all kinds by way of a Saturday Night Live Shatner sketch.

I am sorry that women would feel left out -- that was not my intention. Let's just say that the basic concept of one's D&D activities occluding one's romantic agenda was based on, uh, personal experience (aka high school).

Thanks for all the comments -- it's truly gratifying.
