“It’s really awesome to be here and be invited,” Keanu expressed (via ET). “It’s a great accomplishment, it’s a wonderful film.”

“He’s always been so supportive and so protective of me doing my own thing,” Karina said of her older brother. “I always really appreciate that so. And it was fun to have family here because our mom is out of town still.”
