The 35-year-old musician's new movie, 'Justin Timberlake + The Tennessee Kids', documents the final stop of the star's '20/20 Experience' world tour, and he has admitted he feels apprehensive about its release because he can't hide behind a character.

He told 'Entertainment Tonight': "I'm nervous because there's not a character that I can sort of hide behind."

And the 'Can't Stop the Feeling' hitmaker also admitted he finds it strange that he "takes all the credit" for the hard work that other people put into making the movie.

He said: "You put a bunch of geniuses around you, and then you take all the credit. To take that tour for two years and still have so much fun ... we captured the last two shows and there was still so much good will and love between everybody."

The 'Cry Me A River' hitmaker can't believe how lucky he is to have a career worth being documented on movie, and dubbed the experience as "an embarrassment of riches".

He said: "This is unlike any experience I've ever had. It feels like an embarrassment of riches, really."

Meanwhile, the movie's director Jonathan Demme has gushed about how talented he thinks Justin is, and admits he quickly became one of the star's biggest fans after getting involved with the project.

He said: "What makes my head explode is trying to understand the way this man took all those visual elements and musical elements. How did you do it? How did you dream all that stuff up?"

'Justin Timberlake + The Tennessee Kids' is available on Netflix now.
