DCAU fans may be disappointed to learn that the straight-to-dvd film Justice League: Crisis on Two Earths was originally written to bridge the gap between Justice League and Justice League: Unlimited. It was supposed to be titled Justice League: Worlds Collide. As you can probably guess, the story was taken out of DCAU continuity and retitled. In addition, John Stewart was needlessly replaced by Hal Jordan.

Let me go back in time 7 years and find the energy to be offended.

K.

What is the point of this? Like @jaken7 said, this was a movie that was released SEVEN years ago. And it was a pretty damn good movie.

Yeah, I thought this Was common knowledge. I'm not sure how it's a big deal though. It's not like the movie was set in the dcau and they did it for the lolz. Hal was pretty big at the time and DC wanted to give him some exposure,

This is......old news.
