Justice League: Worlds Collide is the title of an unproduced Justice League direct-to-video film set in the DC Animated Universe. It was originally going to be produced concurrently with the first season of Justice League Unlimited, bridging the gap between the second season of Justice League and the relaunched show. Among other things, the movie would have depicted how Wonder Woman acquired her invisible jet ("For the Man Who Has Everything") and the expansion of the Justice League's membership. The production was canceled just before the start of filming. The plot would have involved the Crime Syndicate as the main antagonists.
On August 1, 2008, Bruce Timm went on record saying there was a good chance fans will be seeing Justice League: Worlds Collide. However, as of 2010, it appears that this specific version of the film will not be made, as the story has been changed into that of Justice League: Crisis On Two Earths, which is not part of DCAU continuity.
- Originally, the Justice League episode "A Better World" was intended to be a "Crime Syndicate story". Eventually the Crime Syndicate became the Justice Lords and the idea was stored for this project.
- The title of the movie is frequently misspelled with an apostrophe as World's Collide.
“ Worlds Collide was going to bridge Seasons Two and Three; besides the origin of the Invisible jet, it also set up the entire super-sized JLU concept. I don't wanna say anymore about it, just in case it ever does get made (there's still a chance, albeit a slim one at the moment, seemingly). ”
— Bruce Timm (circa 2005)
“ Yes, there is a Justice League DTV in the works... kind of. What happened was, the Home Video division commissioned us to write a JL DTV, right around the time we were gearing up for Season Three. Dwayne McDuffie and I came up with the story, Dwayne wrote a terrific script, I designed loads of new characters, we started story-boarding, Andrea Romano had assembled a killer cast, and we were just getting ready to record it, and then Home Video slammed on the brakes, and it was put on the shelf for the time being. This is a good thing, really! The original plan was to do the DTV and Season Three concurrently but, long story short: we would have been stretched way too thin. JLU is a difficult enough show to do by itself, without having to prep a feature-length movie at the same time. Home Video is still interested in making it, apparently, so hopefully it'll happen. ”

“ Fun fact: "A Better World" started out as a straight-up Crime Syndicate story, but evolved into something else while we were 'breaking' the plot. Another fun fact: Worlds Collide, the currently still-on-hold Justice League DTV, featured the Justice League versus (you guessed it) the Crime Syndicate (obviously, we like alternative universe stories, too). Maybe someday ”
