The good news? Fledgling writer James Erwin got Warner Bros. to buy movie rights to a story he posted on Reddit.com about what would happen if U.S. Marines traveled back in time to fight the Roman Empire.
The bad news? Erwin's series of stories - entitled "Rome, Sweet Rome" - first appeared on a website that has a "User Agreement" that might limit the original author's rights.
Apparently, posts on Reddit (Reddit.com allows users to post links and have discussions with each other) are subject to certain conditions. Specifically, according to an Oct. 20th, 2011 post on the Hollywood Reporter, "multiple parties might be able to make a claim to a license if they chose to develop Erwin's story."
