Check out this incredibly cool set of Indiana Jones poster art featuring the original trilogy. The illustrations were created by Andy Helms. I love this franchise, and the more I think about it the more I wouldn't actually mind seeing a fifth film made somewhere down the line. It probably won't happen, but if it did, it would have to be an awesome story. I'd personally like to see a story made about the legend of the Lost Cave City in the Grand Canyon. There's reports of an Egyptian Tomb found their in 1909, you can read more about it here if you're interested.
