Luc Besson, director of the sci-fi film "Lucy" starring Scarlett Johansson, said that developing a sequel for the movie is unlikely, according to The Hollywood Reporter.

The film tells the story of Johansson's character, who, after accidentally ingesting a bag of synthetic drugs, begins to develop various superhuman abilities.

"Lucy" collected more than $17 million in the box office during its opening weekend in the United States. The film earned around $216 million in international sales. It claimed the number one spot in Asia, Middle East and Europe, Variety reported.

Following the film's release, Universal Studios approached Besson to discuss the possibility of developing "Lucy 2." However, the director declined, insisting that "Lucy" was made as a standalone film.

"I don't know how we can do one," the director said. "It's not made for that."

Despite declaring the fate of "Lucy 2," Besson hinted that he is still open to the possibility of making a sequel if he ever comes across the idea worth pursuing.

"If I find something good enough, maybe I will, but for now I don't even think about it," Besson said.

"Lucy" is not Besson's first film that was offered to be turned into a film series. Many fans of his 1994 film, "Leon: The Professional," were hoping that Besson would release a sequel.

Since the main character played by Jean Reno died in the 1994 movie, Besson said the sequel could revolve around Natalie Portman's character. But due to the time difference, Besson is having a hard time developing a proper story for Portman's character, according to JoBlo.

In "The Professional," which was Portman's debut film, the actress played 12-year-old Mathilda, the protégée of the titular hitman character.

"Natalie is old now, she's a mother," Besson said. "It's too late. If I got an idea tomorrow about a sequel, of course I would do it. But I never came up with something strong enough. I don't want to do sequels for money, I want to do a sequel because it's worth it."

"I want it to be as good or better than the original," he added.
