Take a look at 'First Trailer' concept for DC Comics & Warner Bros. movie CONSTANTINE 2 (2024)

While it would have been interesting to see Reeves become part of the DCU as Constantine, it is better for both the new DC Universe and Constantine 2 that the movie is an Elseworlds project. This way, the DCU can get its own comic book-accurate version of John Constantine in the future, perhaps starting with a role in the upcoming Swamp Thing before a full-fledged Justice League Dark film. On the other hand, by not being part of the DCU, Constantine 2 has a lot more creative freedom.
