In a new interview with gay glossy Out, actor-director Robert De Niro says his father was probably conflicted about being gay.

In the HBO documentary Remembering the Artist: Robert De Niro, Sr., De Niro, 70, talks about his father's legacy as an artist.

The senior De Niro, who died in 1993 in New York at the age of 71, was an abstract expressionist painter of the post-World War II era.

Remembering the Artist documents the life of the painter through his son's eyes.

De Niro told Out that the point of the project was to tell the truth. “That's what people are attracted to. I should have done this 10 yeas earlier, but I'm glad I did it now.”

“[Y]our father said he felt like being an artist was an 'affliction,' and he thought being gay was a sort of affliction. Do you think he was conflicted about his life's passion?” Out asked.

“About his homosexuality? Yeah, he probably was, being from that generation, especially from a small town upstate,” De Niro answered. “I was not aware, much, of it. I wish we had spoken about it much more. My mother didn’t want to talk about things in general, and you’re not interested when you’re a certain age. Again, for my kids, I want them to stop and take a moment and realize that you sometimes have to do things now instead of later, because later may be 20 years from now – and that’s too late.”
