Tom Cruise arrived at Dublin's Savoy Cinema last night to premiere Oblivion with his costar Olga Kurylenko. Olga appropriately wore Ireland's national color, green, with her Roland Mouret gown for their latest stop on a European press tour. Dublin welcomed Tom with open arms. Following a reception hosted by the Department of Foreign Affairs honoring his Irish ancestry, he celebrated by pouring pints at the Guinness Storehouse. Tom and Olga premiered Oblivion in Austria Tuesday after stopping in Moscow on Monday and South America last week.
