Age of Ultron offers the most formidable and terrifying Marvel villain yet, but don’t let the seriousness of that threat fool you — the latest featurette for Avengers: Age of Ultron takes you behind the scenes of the upcoming super-sequel, and unsurprisingly, working on this movie was a whole lot of fun (but still exhausting).

Most of the featurettes we see for upcoming Marvel films focus on exotic locations, intricate visual effects and stunt work, the more technical aspects, and introducing new characters. It sounds like so much work. Marvel movies are always fun, so it’s refreshing to go behind the scenes and see the Age of Ultron stars laughing and having a great time working together.

In a way, it’s kind of like Marvel propaganda — see how much fun we’re all having working together as a team! We’re a real team behind the scenes, too! Look at us laugh! Our jobs are so great! Yeah, but their jobs really are the best, so who can blame them?

But as Joss Whedon reminds us, while working with all these fantastic people is delightful, it’s also kind of an exhausting delight. For a film this epic, they had to put a ton of epic work into making it — which will make the end result all the more rewarding for everyone.

In addition, Marvel has revealed two new TV spots, both offering up some previously unseen footage from Age of Ultron, including a new look at a sleek and imposing Ultron, as well as new shots of Iron Man, Thor and Black Widow in action:
