Much like Straight Outta Compton itself, star O’Shea Jackson Jr. exploded on the scene back in August, making his big-screen debut in the film by playing his own father, legendary N.W.A rapper Ice Cube. So what kind of advice did the elder Jackson bestow on his child before the filmmaking process began?

“Be confident. That’s something him and my mother have pumped into all of us,” O’Shea told EW on the red carpet before VH1 Big in 2015 With Entertainment Weekly. “Be confident in whatever you’re doing, because once you start to second guess yourself or have that hesitation, it won’t be your best effort, and there’s nothing you can be pleased with if you don’t give your best effort.”

Ice Cube spent a decade trying to get Straight Outta Compton made, meaning that his 24-year-old son would get the chance to play the rap superstar was never a forgone conclusion. According to O’Shea, however, he didn’t feel any pressure before being offered the role.

“Being on set with my dad — that’s so cool,” he said. “People always ask me if that made me nervous, but it’s the same element when you’re a kid — when your parents come in the auditorium for those school performances. It calms you. When we’re in the room, I know we’re going to takeover.”

Watch O’Shea discuss his breakout 2015 and what advice he would have to anyone on the cusp of stardom next year. VH1 Big in 2015 With Entertainment Weekly airs Dec. 7 at 9/8c on VH1.
