Actor Guy Pearce stars in the creepy new period thriller “Brimstone,” but he’s also been investing his time and energy on a passion project -- his baby boy Monte.

Guy and his partner, actress Carice van Houten, welcomed Monte last August, and Guy says, “It’s a really fascinating thing to fall in love with a baby. It’s amazing, because I never really had a huge interest in having children before. Now I’ve got one and I want 100 of them.”

Monte is “divine” and “laughs at everything,” but he still isn’t the greatest sleeper, so a nice perk of traveling for business is that I get to sleep peacefully in my hotel room, says Guy.

He plays a minister in “Brimstone,” which is about a group of Dutch immigrants who move to America in the 1800s, but his character doesn’t have the best intentions: “He’s clearly using his religious position in the most extreme way to get away with all sorts of things.”

Watch the video below to hear Guy talk more about “Brimstone” and his musical side project. He released his first album Broken Bones in 2014, and is currently working on a new album that features vocals from partner Carice.
