PARK CITY, Utah: Rashida Jones was almost upstaged by her famous father, Quincy Jones, at the Sundance premiere of her film, “Celeste and Jesse Forever,” but the actress and screenwriter didn’t mind.

“He’s what he is and he will always be and has always been, way before I was here,” Jones said Saturday. “I feel lucky to hang out with him. And we’re different, too. People like us for different reasons.”

She added that her dad loved the film, which explores the nature of relationships, marriage and its meaning in society.

Jones’ first screenwriting effort (with co-writer Will McCormack) emerged from “pain, lots of pain.”

“We’re both very deeply feeling people, and we love to talk about relationships and love and feelings,” she said. “We like to be as inappropriate as possible when things are grave and difficult, so I think it probably came from that place. It also came from, as an actress, reading so many scripts, you kind of intrinsically absorb storytelling script structure into your being without even knowing it, and we wanted to try and tell this story.”

Jones stars in the film alongside Andy Samberg, Emma Roberts and Elijah Wood.

She brought her parents and her friends to Friday’s premiere, but unveiling the film was still nerve-racking.

“I felt everything - literally the whole spectrum of feelings,” the 35-year-old said. “It felt 8 hours long. It’s not, it’s short. But it was 8 hours in the way that I was wanting to feel what everybody was feeling and thinking.”

After the premiere, the cast celebrated at a party where Wood served as DJ and danced with Jones’ mom, actress Peggy Lipton.

The Sundance Film Festival continues through Jan. 29.
