Natalie Portman Likens 'Black Swan' To 'Rosemary's Baby' In Terms Of Tone

There isn't too much that's known about "Black Swan," director Darren Aronofsky's ballet dancer drama starring Natalie Portman, Mila Kunis and Winona Ryder. Described by many as a psychological thriller, "Black Swan" has already achieved some notoriety for its purported sex scene between Portman and Kunis, a possibility that Portman herself merely addressed as "not explicit in any way," despite the film certainly featuring some "very extreme situations."

But Portman isn't harping on the alleged sex scene. Instead, she's focused on the film's merits as a psychological thriller, going so far as to compare "Black Swan" to another classic horror movie — "Rosemary's Baby."

"It's very unique in tone," Portman told MTV News at San Diego Comic-Con when asked to describe "Black Swan" in terms of genre and tone. "I think of it more as a psychological thriller, like 'Rosemary's Baby' in [terms of] genre, if I had to pick a genre."

Perhaps the comparison to the iconic 1968 Roman Polanski-directed film is particularly telling, as that movie focused largely on the rapid mental deterioration of the titular Rosemary as she learns that her son could very well be the Antichrist. Does that mean "Black Swan" is going to follow a similar, supernaturally and religiously-charged path? That's hard to say at this point — but it is clear that Portman is enthusiastic about the project, previously stating that she signed on for the movie in order to explore her "adulthood."

"We're really excited about [the movie]," she told MTV. "We just found out that we're opening [the Venice Film Festival.]"
