As a child, Sebastian Stan occupied more countries than most people do houses. At the age of 8, he moved from his native Romania to Vienna, and then, four years later, to New York.
Now 33, Stan doesn't think all that dislocation was always healthy. But it may have given him a certain psychological edge in understanding characters who slip from one guise to another.
"It was hard. You're inhabiting different worlds, speaking different languages," Stan said in an interview recently. "But it helped me in a way. When you're young you just want to fit in. And when you're older you realize that what it really did was make you OK with feeling different."
