With the animated adventures of the original Justice League (Bats, Supes, Wondy etc) concluding at the end of the initial JL animated series, a movie was being lined up to bridge the gap before the team’s roster expanded in super-sequel-series Justice League Unlimited.
OH.SO WHAT WOULD HAVE HAPPENED?
Written by Dwayne McDuffie, When Worlds Collide was set to make use of the concept of alternate worlds already established within the Justice League animated continuity whilst at the same time introducing a few new characters into the mix.The story featured all of the founding members of the League, minus Hawkgirl who had left the show at the conclusion of the three-part story Starcrossed.By the end of the film a few of the League members that appeared in Justice League Unlimited would have put in appearances and things would have been set up to flow right into the opening story of JLU.
BUT WHAT DID HAPPEN?
The story got shelved due to the availability of staff whilst JLU was in production and the script floated around for a while gathering dust.Years later when DC/Warner started producing animated movies based on comic-book inspired stories, the script was flipped open and re-jigged so that it could exist as a standalone tale and was turned into the animated movie Justice League: Crisis On Two Earths.A number of points in the movie made it pretty clear that the film was originally intended to be a continuation of the Justice League series, but Green Lantern member John Stewart was replaced with Hal Jordan so that the most well known GL was part of the team.
WAS THIS SUCH A BAD THING?
To be honest there wasn’t a great deal of detail that needed filling-in between the two series’, so the fact the original script got shelved for a while wasn’t a huge problem.As for all the changes to make it a standalone story, it didn’t make much difference to anyone who had seen the Justice League series as it was obvious that it was written as part of the DC Animated Universe continuity.
BUT WHAT IF?
If Justice League: When Worlds Collide had been produced instead of replacement movie Justice League: Crisis On Two Earths, then it would have created an alternate reality where scripts spawn other scripts and movies become different movies altogether.In that reality Van Helsing (2004) would have been good; Police Academy: Mission to Moscow (1994) wouldn’t have happened; and Free Willy (1993) would have been about another subject entirely.
In all likelihood nothing would have really changed.
