Though they've been around for years, the "button" scene has found a new level of popularity in the 21st century. Ever since Nick Fury introduced himself to Tony Stark at the very end of 2008's Iron Man, moviegoers have become accustomed to seeing extra bits of footage play once the credits have rolled. In the age of shared cinematic universes, it's an entertaining and efficient way of teasing what's next, giving fans one final aspect to discuss as they head out of the theater.
Marvel Studios has made the post (and even mid) credit sequence one of their calling cards, but through the first two installments of the DC Extended Universe - Man of Steel and Batman V Superman: Dawn of Justice - Warner Bros. has stayed away from the tactic. However, the strategy will change with the release of Suicide Squad, which will be the first DCEU entry to include some material that didn't make the film proper.
Per Comic Book, it has now been confirmed that writer/director David Ayer's tale of the Worst. Heroes. Ever. does in fact have a mid-credits scene. It's described by them as "pivotal and important." Once that portion is finished, it's safe for audiences to leave their seats, as Suicide Squad does not have a post-credits scene of any kind. Granted, that could change (these reports are out of advanced screenings) by the time the movie reaches theaters on August 5, but for now there's just one button.
Suicide Squad was already the year's most buzzed-about movie before this news broke, and now there's yet another reason to look forward to its premiere. Given that this will be the first time the DCEU experiments with the button scene, it's difficult to speculate as to what it entails, but viewers will still spend the next week debating what will be shown. From the sound of it, it will most likely be something that connects to an upcoming DC Comics film, perhaps Ben Affleck's solo Batman movie (considering the characters) or the already in-development Suicide Squad 2. Patty Jenkins' Wonder Woman is next up on the release calendar, but that project's World War I period setting makes any connections to Suicide Squad borderline impossible.
It will be interesting to see how many DCEU movies in the future incorporate a mid or post-credits scene. As stated earlier, Zack Snyder did not use one for either of his two works, so this could be something that's left up to the discrepancy of the director. WB has maintained that their massive franchise is going to be "filmmaker-driven" (as much as something of this scale can be), so they may not require all their helmers to adhere to a particular formula when completing their offerings. That kind of variance may be frustrating for some moviegoers who enjoy the additional sequences, but as long as the movies themselves are high quality, there won't be much complaining.
In the meantime, the possibilities are virtually endless for what Suicide Squad has up its sleeve. As revealed in the Batman V Superman ultimate edition, villain Lex Luthor is now an inmate at Arkham Asylum, so the button could set the stage for next fall's Justice League. There's been talk of a Harley Quinn spinoff, which could also be the focus. Some of Marvel's credits scenes have essentially been throwaway jokes (see: Iron Man 3), but it doesn't appear WB is going in that direction. Whatever is shown will have serious ramifications for the DCEU moving forward, and that's an exciting prospect.
Suicide Squad is scheduled to arrive in theaters on August 5, 2016; Wonder Woman is slated for release on June 2, 2017; followed by Justice League on November 17, 2017; Aquaman on July 27, 2018; an untitled DC Film on October 5, 2018; Shazam on April 5, 2019; Justice League 2 on June 14, 2019; an untitled DC film on November 1, 2019; Cyborg on April 3, 2020; and Green Lantern Corps on July 24, 2020. The Flash is without release date.
