"Fifty Shades Darker" will be hitting the big screen by 2016. The previous installment may have made more than $500 million during its premiere, but the lead actress Dakota Johnson still doubts her future acting career.

In one of her interview with Vogue, the 26-year-old actress was filled with gratitude for landing a role as Anastasia Steele. She may have 2 more sequels, the actress however feels worried that she would no longer land a role this huge in the upcoming years.

"It's just insane. I've never experienced anything like it - I don't think anyone has. It's terrifying - and it's exciting,"

Though she may doubt herself and her talents, Director Sam Taylor-Johnson believes that the actress is filled with talent that could take her to places.

"I think it's going to take her to a place where she has witnessed her parents go. Now she's going to experience it for herself,"

The first installation may have made a box office hit, but as for the next two films however, the former director would no longer be making the film. In an interview with US Weekly, Taylor- Johnson opened up about leaving the film in an official statement.

"Directing 'Fifty Shades of Grey' has been an intense and incredible journey for which I am hugely grateful, I have Universal to thank for that. I forged close and lasting relationships with the cast, producers and crew and most especially, with Dakota Johnson and Jamie Dornan. While I will not be returning to direct the sequels, I wish nothing but success to whosoever takes on the exciting challenges of films two and three."

"I'm not going to lie, We definitely fought, but they were creative fights and we would resolve them. We would have proper on-set barneys, and I'm not confrontational, but it was about finding a way between the two of us, satisfying her vision of what she'd written as well as my need to visualize this person on screen, but, you know, we got there."

"I knew how it should be made, needed to be made, and I felt a certain responsibility to make it the right way, I felt it was an incredible story. It's like a dark twisted fairy tale, very romantic, and it was interesting how troubling it was, and how romance and the darkness interweaved."

Realty Today then made a report stating that James Foley would be the one to direct the upcoming installments "Fifty Shades Darker" and "Fifty Shades Freed." Both installments would make consecutive premiere on 2017 and 2018.
