‘Fifty Shades’ vs. ‘Twilight’: Jamie Dornan says they don’t compare

Jamie Dornan and Robert Pattinson are friends. Really.

Your Twi-hard and Christian Grey-loving brains can explode now.

Dornan, who stars in the highly anticipated erotic drama “Fifty Shades of Grey,” and Pattinson, who earned mega-fame playing vampire Edward Cullen in the “Twilight” films are old pals.

“I don’t remember what we talked about the last time I saw him,” the 32-year-old Dornan said of last hanging with the 28-year-old “Life” star in Variety‘s cover story. “I think we just got drunk.”

But that doesn’t mean that Dornan doesn’t appreciate what his colleague endured after achieving worldwide fame.

“I’ve been around Rob long enough to see what it’s been like for him,” the “The Fall” actor and “Once Upon A Time” alum said. “I don’t know if it’s been a benefit to witness that. Whatever that is.”

Dornan has already experienced being hounded by the paparazzi in London, where he lives with his wife Amelia Warner, whom he wed in April 2013, and their 1-year-old daughter.

“I’m astonished at how many people are telling me my life is going to change. Everyone that I meet, especially in L.A. People who run studios or other actors or people who are strangers,” he said. “Everyone has been saying that to me, ‘Are you ready?’ I don’t have a good answer to that, because I don’t know what I’m meant to be ready for. Whatever happens happens. I’ll just roll with the punches.”

His costar, Dakota Johnson, who plays willing college virgin Anastasia Steele in the film, has a similar -- albeit more “terrifying” -- take on the fame game.

“It’s just the most insane thing to be a part of,” she said in the February issue of Vogue. “I’ve never experienced anything like this; I don’t think anyone has. It’s terrifying -- and it’s exciting.”

Incidentally, E.L. James’ best-selling “Fifty Shades of Grey” trilogy was inspired by the “Twilight” trilogy. The broody bestselling books already had built-in audiences for the films and Pattinson was even considered for the lead role of dominant sexpot Christian Grey. But Dornan, who clinched the role after “Sons of Anarchy” star Charlie Hunnam dropped out, thinks the two franchises don’t compare.

“By the way, it’s not the same thing,” Dornan insisted. “We’re not the Twilight franchise. We’re a different thing. Whatever my situation is, it’s going to be different from Rob’s. They are incomparable.”

Vampires vs. sex-addled billionaires. Yeah, totally different.

“Fifty Shades of Grey” dominates theaters on Feb. 13.
