To celebrate the end of filming in the United Kingdom, Justice League director Zack Snyder has released a trailer of sorts which finds the cast having a ball.

Whoever said the world of DC is dark? Look, everyone, this new featurette proves that everyone is having fun on the set of Justice League! (But seriously: It’s a well-cut preview — it’s filled with fun and rock and roll.)

“Last day filming in the UK,” Snyder wrote on Twitter. “It has been an amazing shoot. Big thanks to everyone involved!”

The preview doesn’t only show goofing around: We also see the members of the Justice League uniting and taking care of business. It’s one of the most exciting looks yet at the new film, which is slated to hit theaters next fall.

Batman v Superman: Dawn of Justice received a lot of flack for being too dark, and Warner Brothers seems eager to change up perceptions for the follow-up.

The following is a Justice League synopsis from Warner Brothers:

Fueled by his restored faith in humanity and inspired by Superman’s selfless act, Bruce Wayne enlists the help of his newfound ally, Diana Prince, to face an even greater enemy. Together, Batman and Wonder Woman work quickly to find and recruit a team of metahumans to stand against this newly awakened threat. But despite the formation of this unprecedented league of heroes—Batman, Wonder Woman, Aquaman, Cyborg and The Flash—it may already be too late to save the planet from an assault of catastrophic proportions.

The movie opens in theaters November 17, 2017.
