A documentary based on pop singer Britney Spears is one step closer to the screen and will be on Netflix. A trailer teaser for the film `Britney Vs. Spears` confirms, reports variety.com. In the 18-second clip, Spears is heard leaving a message for an attorney in 2009. A trailer is expected to drop on Wednesday, September 22 and the documentary itself on September 28 ahead of Spears` next court date on September 29.

The documentary is being directed by Erin Lee Carr and has been underway for more than a year. The documentary is said to center around Spears` highly-unusual conservatorship, and will feature key figures in Spears` orbit. It is unclear, though highly unlikely that Spears herself will appear in the project, given how closely guarded she has been from media opportunities throughout the course of her conservatorship.
