Asked by reporters at the Berlin premiere of his film "Behind the Candelabra" about his separation from Zeta-Jones, Sky News quoted Douglas as saying: "I have a crisis at home? No, I think the press has a crisis. We are fine. My wife and I are fine. We [are taking] a temporary separation -- but the press, it gives you stuff to write about."
Douglas, 68, and Zeta-Jones, 43, were married in 2000 and have two children together.
Media reports saying the couple split up surfaced last week. The news comes after Douglas recently battled throat cancer and Zeta-Jones was treated for bipolar II disorder.
