Seventh Son brings, as co-star Julianne Moore describes it, a “crazy, fantastical world” to life. Shapeshifting witches, prophesied heroes, and all manner of monsters make their way through the tale, a mystical quest inspired by Joseph Delaney’s novel, The Spook’s Apprentice.

To find out what went into the making of this world, editor in chief Brian Walton met with the cast — Moore, Jeff Bridges, and Ben Barnes — to talk adventure theme songs, dragon-inspired costumes, playing “pass the pigs” (?) between takes, fight choreography, practical sets, and more.

And for even more Seventh Son fun, join Jeff Bridges in a game of “2 Truths & a Lie”, exclusively on the Nerdist Channel on YouTube:

Seventh Son is out in theaters today.
