The Confessions of a Shopaholic star met Danes on the set of their 2007 movie Evening and they married in France in 2009.
Dancy admits they split their time between New York and London, but they try to co-ordinate their schedules so they can be together as much as possible.
He tells Britain's Press Association, ""I could be in London. I could be in New York. Same is true of (Claire). She's worked in London more than I have, as a matter of fact, and I've worked in New York more than she has. The occasional challenge is matched by the great opportunities and advantages... I've been lucky enough to chart a kind of strange course in between. I've been able to do it enough so far.""
