Snippet from article today:
David Hewlett has been cast in The Whistleblower, an independent film starring Rachel Weisz...
The independent film begins shooting next week in Romania, and tells the story of a Nebraska police officer who outed the U.N. for covering up a sex trafficking scandal while serving as a peacekeeper in post-war Bosnia. The movie is based on a true story.
Hewlett (SGA's "Rodney McKay") plays an American U.N. peacekeeper posted in Bosnia, who is suspected of being involved in the scandal
