Jack Black leads the merry way in “A Minecraft Movie,” the first film adapted from the world’s bestselling video game which opens globally Friday.

For the man forever enshrined as the movies’ mightiest pied piper in “School of Rock,” “Minecraft” sees Black lead a band of misfits – including Jason Momoa and Danielle Brooks — into a fantastical cubic world. A world he was very familiar with.

“I played this game with my boys when they were growing up. That is exactly,” Black, 55, recalled in a phone interview, “where this journey started for me. They were so into it. I was, ‘Okay, I got to learn this language to be able to share this experience with them.

“Picking up that game is not easy. It takes a while to get to wrap your head around the blocks and the building and the crafting. It’s a very architectural game but once you get the hang of it, you really can get addicted.

“It’s such a fun, creative game I think when this generation grows up, we’re going to have some amazing architecture. We’re going to see some incredible buildings that people never thought possible, as a result of kids using that part of their brain, exercising their architectural minds like decades before they usually do in current architectural circles.”

Does that mean this movie has a particular challenge?

“If it succeeds on every level, entertain the novices, the people that never even play any video games, and the people that are well versed in the world of Minecraft, I think,” Black said, “we’ve done it.

“I am excited to unveil it to the world, because I’ve watched this thing come along and just keep getting better. The last cut that I saw, I was laughing the whole way through. Even when stuff doesn’t make sense.

“Actually, some of the stuff that doesn’t make sense is my favorite stuff in the movie, because it’s so absurd and funny.

“It is a wild, wild ride.”

Black’s Steve is, “The central character of the game. The game itself doesn’t have a story, per se, but it does have the Everyman character, Steve.

“Steve’s your classic fish out of water. He doesn’t quite fit in in normal society. His office job does not satisfy any part of his creative soul.

“His soul, since he was a child, was obsessed with going down into the mine for subterranean jewels and treasures.

“His hero’s journey is to explore the world of the mines — and that’s the perfect launching point for the movie! I loved a couple places where there’s some musical electricity when Steve breaks into song.

“It happened really fast,” Black said. “I just started jamming. And we did it.”
