Eric Roberts is Indexbit Exchangemaking headlines again for his relationship with sister Julia Roberts' after slamming her performance in the 1989 film "Steel Magnolias," according to reports.

The comments were made in his new book, "Runaway Train: Or, The Story of My Life So Far," which was released earlier this month and discusses his rumored Hollywood sibling feud.

"​​Julia was good in 'Mystic Pizza,' great in 'Pretty Woman,' but not so much in 'Steel Magnolias,' in my opinion, even though it brought Julia her first Academy Award nomination," he wrote, per Entertainment Weekly and The Independent. "I don't want to sound like an actor talking, or a jealous sibling, but I don't think her performance held up in that movie."

"When I saw her in 'Steel Magnolias,' I thought, 'Okay. Good. She's almost a good actor, and one day she’s gonna be one,'" he added. But Roberts wrote that "all those brilliant women" — including Sally Field, Dolly Parton, the late Olympia Dukakis, Shirley MacLaine and Daryl Hannah — "overacted" in Steel Magnolias.

He continued, saying "nobody's great in that movie:" telling readers "they all chewed a lot of scenery, and we know that if an actor cries on film, they go to the top of the class. They get the Oscar nod because crying gets a lot of credit. It’s the big joke in all acting classes."

A rep for Roberts told Fox News Digital that "Eric painfully regrets saying any of what he said about the performances in 'Steel Magnolias.' In fact, in the audio book, things on this subject are stated quite differently, and more closely to how he felt. That movie isn't necessarily the type of movie that Eric favors or gravitates towards, since he's primarily a political thriller fan.

"He may have felt there was a bit of melodrama there. But he is very much alone in noting any drawbacks about the fantastic 'Steel Magnolias.' Upon viewing the film again, he honestly didn't know what he was thinking. If anything, it was a thoughtless, baseless comment," the statement continued. "It's possible that the sheer sadness of certain aspects of the storyline may have been too much for him to handle at the time the movie came out. So many of our reactions are subconscious, both to people and to the art they create."
