In Waltz With Bashir director Ari Folman opened our eyes to new ways animation can be applied to dramatic true-life stories. Now, Folman returns with a new film, a sci-fi fantasy, that may not be very far from becoming reality. 

Here's the international trailer for his latest, The Congress, based on Stanislaw Lem's The Futurological Congress. Starring Harvey Keitel and Robin Wright, it opens the Directors Fortnight at the upcoming Cannes Film Festival.
