I haven’t see I AM LEGEND yet, a good buddy of mine tipped me off to this little nugget after he saw it. I don’t think this is anything more than Warner Bros. using the properties they own in unique ways.
The hopeful geek in me on the other hand thinks that this could be an early warning of things to come. It is a fact that Warners is continuing their SUPERMAN and BATMAN films , even putting the characters on the same big screen in George Miller’s JUSTICE LEAGUE movie due out in 2010. Wolfgang Petersen was involved in doing a BATMAN VS. SUPERMAN movie before Brian Singer’s SUPERMAN and Christopher Nolan’s BATMAN went ahead, so we know that Warner Bros. has this concept on the brain.
