The first look at Trollhunters revealed a show that looked like it was going to balance big doses of humor, action, and worldbuilding. A new video featuring the director and cast gives a hint at the thinking behind the upcoming series.

Maybe it’s the way that it’s promising a deep mythology, but something about Trollhunters comes across as a throwback to older animated action shows of the past. In the video above, Del Toro and the cast talk about his aesthetic aims for the Netflix offering, which debuts on December 23.
