MOVIE PREMIERE: Last year, director Laura Poitras, the filmmaker behind the fascinating Citizenfour, premiered her documentary film on WikiLeaks founder Julian Assange at the Cannes Film Festival. This is its TV debut – and for the occasion, Poitras has updated Risk by adding new footage tied to the 2016 presidential campaign – during which WikiLeaks dumped thousands of hacked emails from the Democratic National Committee, an action which continues to generate headlines top this day.
