The first trailer for the upcoming Batman & Harley Quinn film has finally arrived. In a truly unexpected turn of events too, the film is the next title set to be released from the animated side of Warner Bros.' DC projects, as it brings together its unlikely titular duo on a mission to bring down some of Gotham City's most notorious criminals. Warner Bros. isn't pulling any punches with Batman & Harley Quinn either, after not only casting Big Bang Theory star, Melissa Rauch, as Harley Quinn but also bringing back Kevin Conroy to play The Dark Knight yet again.

Capitalizing on the current overwhelming popularity of the Harley Quinn character, the film is being sold so far as more of a parody on classic 1980s buddy cop films than a traditional comic book adaptation. That might seem strange at first - but when considering the dynamic that Batman and Harley Quinn have with each other, it's hard to think of a better route for Batman & Harley Quinn to take.

After a couple of weeks with no new updates or announcements from the project as well, EW has officially released the first trailer for Batman & Harley Quinn online today. The trailer itself finally lifts the lid on the main plot of the film, which follows Batman and Nightwing when they are forced to team up with Harley Quinn, after Poison Ivy (Paget Brewster) and Floronic Man (Kevin Michael Richardson) embark on a quest to turn millions of human being into plants. Check out the trailer for yourself in the player above.

Batman and Harley Quinn have emerged as one of the more unlikely fan-favorite pairings in DC comics history, after interacting with each other from time to time throughout the past several decades since her original creation in the 1990s. And it's not hard to see why, since often times whenever Harley and Batman run into each other and The Joker isn't involved, it leads to some genuinely entertaining banter and moments between the two characters.

As a result of the inherently odd quality of the pairing itself, Batman & Harley Quinn looks to be one of the more comedic animated films that DC has ever released. And fortunately, the trailer doesn't give too many of the jokes away, instead opting to take the time to set up the main reasons that bring Batman and Harley Quinn together, before diving into a quick montage of moments between the two characters. Unsurprisingly, most of the conversations appear to focus mostly on Batman's genuine horror at having to interact with Harley in the first place, while she remains hilariously oblivious to his problems with her.

All things considered then, a buddy-cop film between Harley Quinn and Batman may not have been the animated film that most fans would have expected DC to make - but it looks to be a nice change of pace from the studio's more dramatic and darker outings as of late.
