The biographical film "Amy," set to be released on Friday, will take the viewers back into the life of the British songwriter — how she started as a Jazz singer to becoming a global sensation to her death.

What sets this documentary film, directed by Asif Kapadia, apart from the others?

Here are three notable facts:

1. Kapadia was given by Universal a full creative control on the movie.

The full creative control is one of the reasons one reason why "Amy" is more interesting than the usual official biographies. Universal commissioned the movie and gave Kapadia complete access to her musical catalog.

This compilation gives the audience the capability to follow her through her music, not just through the testimonials of her family, friends and colleagues, according to a review posted on Daily News.

2. Kapadia was provided with an exclusive access to Winehouse's archives.

This "Far North" director beautifully pieced together images exclusively taken from Winehouse's archives, including videos, public interviews, recording sessions and concert materials into a film.

Kapadia was also able to obtain a 12-hour video containing the day-to-day activities of Winehouse and her friends, including their sleeping and waking hours, backseat and backstage respites. A review posted on The New York Times stated that the movie felt like a diary because of the personal documentation.

3. Kapadia's film is raw.

The director presented two sides of Winehouse — before and after fame hit her hard. Viewers will get to know the shy, funny and charming side of the "Black in Black" singer.

He also offered ample evidence of how she developed self-destructive impulses, in the latter part of her Hollywood life. He straightforwardly presented the reality that, photo by photo, the public has been watching the "Back in Black" singer die.

Secret Cinema in UK, with a special screening of "Amy," launched the Secret Cinema X platform, Monday. The platform's concept is to screen cult classics and exclusive previews in secret locations.

The screening took place at Koko, a night club where Winehouse performs regularly, Billboard reported. Before and after the film, her former band made a performance.

Winehouse died in 2011. It was reportedly because of alcohol intoxication.
