Man from U.N.C.L.E.'s Armie Hammer Reveals Why He 'Would Make a Terrible Spy' in Real Life

While Armie Hammer plays a convincing KGB operative in The Man from U.N.C.L.E., the 28-year-old actor doesn't think he would fare so well in real life.
"I know for a fact I would make a terrible spy," he tells PEOPLE in this week's issue. "Everything that I have works against me."
"Everything" being his height, of course (which is even joked about in the movie). Standing at a staggering 6'5", Hammer thinks he might be "way too tall to blend into a crowd."
Even if he could go unnoticed, the Social Network actor claims he has a total inability to sit still for long periods of time – not to mention his habit of being a little too honest.
"I'm not the world's best secret keeper," he explains. "I would have a few drinks and then be like, 'Hey guess what, I'm a spy!' Then I would probably get killed."
Hammer stars as KGB agent Illya Kuryakin alongside Henry Cavill, who plays CIA agent Napoleon Solo. The two must put aside their longstanding hostilities to stop a mysterious international criminal organization and prevent worldwide catastrophe.
The Man from U.N.C.L.E. hits theaters Aug. 14.
