Eric Roberts Says He Would 'Love' Sibling Julia Roberts to 'Play My Sister' in a Movie

Eric Roberts wants to share the screen with little sis Julia Roberts.

Speaking with The Hollywood Reporter, Eric, 66, said he would "love" to do a movie in which Julia, 55, plays his character's sister. He added that he'd also be interested in doing a father-daughter movie with his real-life actress daughter Emma Roberts.

"Are you kidding, I would love that. I'd also love my sister to play my sister," said Eric, whose 1989 movie Blood Red also starred Julia.

Eric said seeing Emma, 31, become a movie and TV star has been "so much fun." "And," he continued, "she's never had any training, so she's been on-the-job training her whole career, and it's been lovely for me to watch her become and actor, and she has. I love her work."

"I'd write the wardrobe tags and organize the makeup brushes and watch how they did their continuity books. I would ask questions without a filter. This industry really is 'learn as you go,' " she explained.

Emma added that she didn't feel pressured to emulate Julia's career: "I never aspired to be her. I love her so much, I love her work, but I'm just doing my own thing."
