Warner Bros. has set two unspecified event films for release in 2019 and 2020, adding to their already-massive release slate over the next few years. These projects could be sequels to any other property the studio controls or perhaps a new title the studio has not yet unveiled, but there is another possibility. There is already speculation that one of these dates could be for Ben Affleck's new Batman reboot.

Exhibitor Relations revealed the news on Twitter today, with the studio setting dates for these mystery movies on September 27, 2019 and February 7, 2020. As of now, there are no other movies set for release on those dates, or even those months as a whole. The 2019 project comes between two more Warner Bros. projects, another untitled event film on August 1, 2019, and an untitled DC Movie on November 1, 2019. The February 7, 2020 project comes between an untitled Sony Pictures Animation franchise movie set for release on December 25, 2019, and an untitled Pixar movie set for March 13, 2020.

As for The Batman, we know that Ben Affleck is set to star in and direct from a script he co-wrote with Geoff Johns. Time Warner CEO Jeff Bewkes announced earlier this month that this movie is a "year and a half out," which would place it around spring 2018, although the studio has still not confirmed an exact release date, or revealed when production would begin. It's possible that the studio has shifted this project, entitled The Batman back to either the 2019 or 2020 date that was announced today. If these dates are for The Batman or any other DCEU film, it could signify that Warner Bros. is planning on releasing upwards of four DCEU movies per year in 2019 and 2020, which is something not even Marvel has accomplished yet.

Exhibitor Relations also noted that the last Warner Bros. event film to be unveiled was Ocean's Eight, which the studio had placed in its previously-set June 8, 2018 release slot. It's possible that the 2020 date could in fact be for Fantastic Beasts And Where to Find Them 3, since the studio had previously announced that sequels to Fantastic Beasts And Where to Find Them, which hits theaters on November 18, will arrive in 2018 and 2020. Then again, a February date for this trilogy finale may not work, especially since the studio has set a November 16, 2018 date for Fantastic Beasts 2.

It's possible that one of these dates could be for Creed 2, although MGM CEO Gary Barber revealed at the Golden Globes earlier this year that he hopes to release the sequel in late 2017, two years after the release of the first movie. However, director Ryan Coogler and star Michael B. Jordan will both start shooting Black Panther in early 2017, which would make it difficult for the sequel to reach that November 2017 date, even if Ryan Coogler doesn't come back to direct. A 2019 or 2020 date for Creed 2 will allow both the director and star ample time to shoot Black Panther and return for Creed 2.

These dates could also be for new LEGO projects as well. The studio will release The LEGO Batman movie on February 10, 2017, followed by The LEGO Ninjago Movie on September 22, 2017 and The Lego Movie Sequel on February 8, 2019. It's possible that these two dates could be a combination of any possibility listed above, so we'll have to wait and see. Take a look at Exhibitor Relations' tweets below, as we wait for more details on these new Warner Bros. release dates.
