Actress Zoe Saldana had finished filming the controversial filming of the Nina Simone biopic, "Nina". The film has been the subject of much criticism since the movie has been in limbo for a long while now.

In an interview with Latina, the star of "Guardians of the Galaxy" talked about the reasons why the release of the biopic "Nina" was delayed and that Nina Simone deserved so much better than the treatment that she was getting.

"The people behind the project weren't my cup of tea," said Saldana. "The director [Cynthia Mort] was fine, but there was a lot of mismanagement, which is why we're still here three years later. And I'm still trying to fight with everybody to get the movie finished. Nina deserves better."

The actress, who is of Dominican and Puerto Rican ancestry, had caused a slew of controversy when she was cast to play the role of the African-American civil rights activist. Saldana would insist on portraying the civil rights activist. The 37-year-old actress had even gone on a self-imposed retreat in order to prepare for herself emotionally, mentally and physically for the role at hand.

Saldana also said that she was "haunted" by the role of Nina Simone, and admitted that she never found it difficult to empathize with another woman. She still felt upset over how things were and felt like the delay in the film was doing an injustice to the African-American singer.

"To this day, I can't listen to her music. I'll be able to listen to her and not feel so heartbroken once I either finish this movie and release it, knowing that we did the best we could, or this movie goes away," said Saldana of the film's controversial delay.

The "Avatar" actress also said that preparing herself for the role of the civil rights activist was intense and was perhaps one of the most exhausting roles she had to prepare for.

"I listened to her voice, to her tone. She was angry -- and rightfully so. She was a black woman born ahead of her time. Her soul, her spirit was never able to accept or adapt to the heartbreaks that life was giving her," added Saldana.

A report with Indie Wire said that Mary J. Blige was initially attached to the film while it was still in development six years ago. Saldana was later attached to the film because she gravitated towards more international box office success.

Director Cynthia Mort was earlier seeking monetary damages for an undisclosed amount, as well as "a declaration that the defendants can't make decisions without her meaningful approval and consultation."
