Right now you can bid on ebay for a extra part on the next Spider-Man movie. Question: if you buy an ebayed spot in Spider-Man 4, can we blame you when Sam Raimi makes the audience do a jazz hands salute to the third one? eBay is hosting an auction for Spider-Man 4 (which is currently going for around 5K) but according to the post, all the proceeds go to charity Stand Up To Cancer. But wait, there’s more. The eBay auction includes a set visit for the day (plus you’re allowed to bring a friend), a meet and greet with the cast for one whole hour (which is actually a really long time to have to hang out with Kirsten Dunst), a walk-on/extra role, a trip to the premiere, and outfits for said premiere (apparently you can’t wear spidey PJs). I’m all for using scifi for a good cause, so if you’ve got the cash, go for it. Bidding ends Sept. 5.
