WikiLeaks founder Julian Assange may be locked inside the Ecuadorian Embassy in London, but he still remains one of the most popular whistleblowers of our time. Case in point, DreamWorks’ The Fifth Estate, an upcoming film that chronicles the early days of the infamous website, and also the relationship between Assange and colleague Daniel Domscheit-Berg. The studio has released the first trailer for the film, check it out.

Based on Domscheit-Berg’s book Inside WikiLeaks: My Time with Julian Assange at the World’s Most Dangerous Website and David Leigh and Luke Harding‘s WikiLeaks: Inside Julian Assange’s War on Secrecy, The Fifth Estate is directed by Bill Condon and stars Sherlock star Benedict Cumberbatch in the title role.

In the first trailer we see that Cumberbatch has fully-immerse himself in the role of Assange. The actor’s hair is fully blonde, and his speech pattern is uncanny. The clip sets up the movie rather well, but doesn’t give too much away. We see that Assange started out as a visionary, but somewhere along the way, his ambition got the best of him.

Assange has already demonized the film as “a massive propaganda attack on WikiLeaks and the character of [his] staff.” But, he may have spoken too soon. A film like this may actually broaden the public’s knowledge of, not only WikiLeaks, but also whistleblowing in general.

The film also stars Daniel Bruhl, Alicia Vikander, Stanley Tucci and Carice Van Houten, and hits theaters October 11.

What do you think of Cumberbatch’s impression of Julian Assange?
