Well before HBO canceled “Enlightened” last month, a lot of people saw it coming, and one of them was star Laura Dern.

She knew that the show’s heroine, obsessive whistleblower Amy, was not the prime-time norm.

“Angry women scare men. Crazy women — forget it,” Dern said with a laugh a few weeks before HBO lowered the ax. “It’s OK if you play sexually crazy or sexually complicated. Sexy addict? Hollywood loves it!”

Case in point: Her character in 1991’s “Rambling Rose” — “a complete nympho,” Dern said. “And to this day, all the boys tell me, ‘She was so troubled, but for some reason we just love her.’ ”

An even bigger hit from her past, the dinosaur epic “Jurassic Park,” is being released in 3-D on Friday.

“It’s phenomenal, and the 3-D is awe-inspiring,” Dern said. “This release will remind people that this is a great film. I saw the movie with my 11-year-old, which was seeing it through new eyes.”

The 46-year-old actress is keeping busy, defying expectations about aging in showbiz.

“A lot of women are proving that working as an actress when you’re over 40 is actually legal in Hollywood,” she says. “And you can do this outside of France, where it has always been legal even to work over 60.

“Thanks to cable TV, there is a great tribe of ladies who are getting this crazy good work now. We can play wonderfully complicated women, and there isn’t an ingénue in the group.”
