LEGO DC Comics Superheroes: Justice League: Gotham City Breakout

While The LEGO Batman Movie might be the big LEGO DC event of the year, LEGO's ongoing partnership with the comic book industry is going to result in another feature-length film before Batman's big-screen outing. If you like titles filled with colons, you're in luck with LEGO DC Comics Superheroes: Justice League: Gotham City Breakout. While we don't have a date for this small-screen outing yet, we do have a description and a trailer.

We're told that:
Fighting crime is a full-time job and Batman NEVER takes a vacation. That is until he finally agrees to let Batgirl and Nightwing take him on a long overdue trip – leaving Gotham City under the watchful eye of the Justice League in LEGO® DC Comics Super Heroes - Justice League: Gotham City Breakout. 
  When Batgirl and Nightwing take Batman on a trip down memory lane – literally – to visit one of the key mentors from his formative years, it’s up to the Justice League to keep Gotham City crime-free. But neither situation proves to be a “vacation” as the Bat trio encounters old nemeses on their adventure, and the Justice League discovers just how busy Batman is on a regular basis. It’s a brick-tastic battle on two fronts as Batman, Batgirl and Nightwing take on Bane and Deathstroke, while the Justice League – with some help from a few Teen Titans – fends off an assault by many of Batman’s infamous adversaries to ensure Gotham City’s safety.
