To celebrate reaching the monumental achievement of 1 million subscribers on their All-Access Youtube Account, DC Comics will host an 8-hour entertainment livestream with comic book creator interviews and more.
DC will host this 8-hour event on September 2nd and it will consist of a number of features, but it seems like there will be a focus on the comic books, with interviews from comic book creators being the first released information. However with the recent developments in the DC Extended Universe (and the many references in your face in Suicide Squad to Justice League) it is not beyond the realm of possibility to imagine that we might get some news.
In fact I would stake heavily that DC's marketing team are using this as a way to really generate some excitement for both their comics and their film series in a very heavily Marvel time of year (with Doctor Strange coming up and another Marvel Netflix series released in September). We at Casual Critic will cover as much of the material released regarding the movies and any relevant material, like hints or info releases regarding what is coming up in the DC EU, so stayed tuned to Casual Critic for all the latest.
