The night is dark and full of terrors, even for Kubo and the Two Strings. A new behind-the-scenes look at the stop-motion-CG hybrid reveals how some of these terrifying stop-motion beasties came to life.

Kubo, featuring the voices of Charlize Theron and Matthew McConaughey, will introduce moviegoers to The Moon Beast, the Garden of Eyes, and the giant skeleton in The Hall of Bones.

Animator Charles Greenfield said he was initially “nervous and a little bit scared” to work on the latter, but he ended up creating an oversized model for the production. The same goes for the multi-eyed, 8-feet-tall underwater creature, which was partly built using the transparent globes that hold bingo balls.

According to the featurette, “Stop-motion has a great legacy of bringing creatures to life. In a way, it’s like an homage I think to all stop-motion monsters — but ours are better.”

Kubo tells the story of a young boy with mystical abilities who sets out on an adventure to stop an evil he inadvertently unleashes. Art Parkinson from Game of Thrones voices the title character, while George Takei, Ralph Fiennes, and Rooney Mara’s voices are also features.

The film will hit theaters on Aug. 19. Watch the featurette above.
