By now, fans of the trilogy who've seen the trailer have revisited the lustiness they experienced while reading James' novels, which started off as "Twilight" fan fiction and has since been dubbed "mommy porn."
So what was it like filming those racy sex scenes?
"I do, a lot," Johnson quipped.
"It's more about visually what our bodies look like and what we're doing," said the 24-year-old daughter of
Dornan, who has received praise for embodying the sexually charged billionaire after "Sons of Anarchy" star Charlie Hunnam dropped out of the role, said that he could see himself in Christian: "There's always something about any character that you play that you're drawn to because you feel that it relates to something within you."
There's been talk of "watering down" the book's raunchy narratives in order to achieve an R rating rather than an NC-17. Though James, who's been heavily involved in the film's production, didn't speak specifically about the rating, she did say this about those provocative liaisons: "It's happening."
"What I've seen hasn't been particularly watered down, so, um, yeah ... I thought it was interesting! So that's all I'll say about that," James added.
Meanwhile, Beyonce has recut her 2003 hit "Crazy in Love" for the film and teased to it on Monday, prior to the trailer's release.
"Fifty Shades of Grey" will hit theaters on Valentine's Day 2015. But we won't judge you if you watch the trailer over and over till then.
