nullAnas Aremeyaw Anas is an acclaimed, award-winning Ghanaian investigative journalist (print and documentary), famous for using his anonymity (he does not show his face in public, opting for masks and disguises) as a tool in his investigative reports that usually tackle human rights and anti-corruption issues in sub-Saharan Africa.

His lauded investigative works (at times potentially life-threatening) have made him an internationally-known figure, so much that in a 2009 visit to Ghana, in a speech, President Obama spoke of Anas and his contributions to journalism, as well as the causes he fights for.

And now, Anas is at the center of a new feature documentary from director Ryan Mullins, titled "Chameleon," which takes audiences deep undercover with one of continental Africa’s most famed investigative reporters, to watch him in action, dispatching his own brand of brazen journalism.

Director Mullins is a Montreal-based filmmaker, director, editor and cinematographer, whose last work was one he shot and directed, titled "Volta" (about a derelict cinema in rural Ghana), which premiered at the 2009 Toronto International film festival, and South by Southwest in the US.

He was awarded the Scholarship for International Development Journalism by the IDRC and nominated for the Bell Fund’s "Ten to Watch" in new media.

The film is set to make its North American premiere at the Hot Docs Canadian International Documentary Festival, which runs from April 23 to May 3, 2015.
