"I've been away for a while, but everything should hopefully be on the up and up," Douglas said during his appearance on The Tonight Show. "Sometimes people take a little bit of a break, but it doesn't necessarily mean that's the end. So I'm very hopeful."
Douglas, 69, and Zeta-Jones, 44, announced in August that they were separating, but not seeking a divorce. They've been married since 2000 and have two children together, ages 13 and 10.
At the time of their separation announcement, a source close to the couple said that Zeta-Jones' struggles with bipolar disorder and Douglas' battle with throat cancer(which was later revealed to actually be tongue cancer) were to blame for the strain on their marriage.
Watch Douglas' comments below. Do you think he and Zeta-Jones will be able to work things out?
