From the "Us" trailer which has social media buzzing.

ENTERTAINMENT WEEKLY: Why did you decide to use Luniz’s “I Got 5 On It”?

JORDAN PEELE: That song, it came pretty simple, I’m making a movie in Northern California, that’s a bay area hip-hop classic and I wanted to explore this very relatable journey of being a parent [and] maybe some of the songs you listened to back in the day aren’t appropriate for your kids. So that was one level, and another part was, I love songs that have a great feeling but also have a haunting element to them and I feel like the beat in that song has this inherent cryptic energy, almost reminiscent of the Nightmare on Elm Street soundtrack. So those were the ideas that that song hit the bullseye on for me, and also, it’s just a dope track.
