Tom Cruise was joined by his costars Andrea Riseborough and Olga Kurylenko at the world premiere of Oblivion in Buenos Aires, Argentina, yesterday. He wore a suit while Andrea donned an Elie Saab Couture dress. Tom posed for photos with fans on the red carpet ahead of the event, and even retweeted snaps of his Argentinean fans waiting for his arrival. This premiere marks a first for Tom, who has never opened a project in the country. Oblivion's publicity tour isn't over just yet, as Tom will be traveling to Russia to do promotional work before returning to the States for the US premiere.
