Ian McKellen will tell the complete story of his life in a new docu-series called McKellen: Playing The Part.

The series, directed by Joe Stephenson, is based on an exclusive 14-hour interview with McKellen.

According to Variety, it will include "rare archive material of early work from stage and screen, never-before-seen photography from McKellen’s private collection, and cinematically reconstructed scenes from his life."

The out British actor has been nominated twice for an Oscar and five times for an Emmy. He's also a tireless LGBT advocate, and went viral in January for his comments on why no openly gay man has ever won an Oscar for Best Actor.

"I wonder if that is prejudice or chance," he said at the time.

"To a whole generation of cinema-goers Ian is known as Gandalf and Magneto, but here is an opportunity to show them his incredible, and inspiring trajectory from his modest childhood in the north of England to Tony winning star of the stage, from one of the first actors to speak openly about his sexuality to becoming an internationally recognized two-time Oscar nominee," Stephenson said of the new series.

"We wanted to talk candidly to him about his journey and philosophy in a way that may not have been done," he added.

"My hope is that an audience might walk out of the cinema as inspired by his journey as I am."
