This is an interesting topic. I'd love to see more of these.
By the way, TJ: from Ask Wizards, May 13th, 2002:
Q: "I noticed a Magic Invasion poster on Peter Parker's wall in the new Spider-Man movie. Was it a paid advertisement on Hasbro/WotC's part or is it pure coincidence that the geeky Peter Parker plays Magic?"

A: From Scott Rouse, Magic Marketing Manager:
"Peter Parker has been a huge Magic: The Gathering player for a number of years. In fact, prior to the incident at the lab with the genetically engineered arachnid, Peter was trying to qualify for the Pro Tour. With his new role as a crime fighter, he has less time to play with the fellas down at Neutral Ground, but I hear he has been doing some late night beta testing for Magic Online.
"Seriously though, movie production designers will often place props into a scene to create a more realistic environment. The producers of the Spider-Man movie thought Peter Parker would be the type of person who would play Magic. In December 2000 the Spider-Man movie production team contacted us looking for Magic and D&D items to place in Peter Parker's bedroom. I jumped at the chance to get Magic products in a sure-to-be blockbuster movie about one of the best superheroes ever. That same day I sent a package of cards, novels, binders, and posters off to Columbia Pictures. We would have to wait over a year to find out if they used any of the items we sent. In the September 2001 issue of Wizard Magazine, a sneak peek look at Peter's movie set bedroom confirmed the use of a D&D poster but there was no mention of anything from Magic. When the movie was released we were very excited to see they had used an Invasion poster in Peter's bedroom. We did not pay a fee for the placement of the posters in the movie, although that is a very common practice in the entertainment industry."
