The Just Married actor, who wed Moore in 2005, admits he has gone to great lengths to prove his devotion to the actress, although even the "simplest, easiest" thoughts can keep a romance alive.
He tells Britain's OK! TV host Matt Johnson, "It was worth it. I just think that sometimes romance is only doing something that's a little bit uncomfortable.
"Romance can be the simplest, easiest thing, but it's really just about doing something that's uncomfortable for you. So if you don't know how to cook and you cook for someone, you're willing to make that fool out of yourself, that can be a very romantic thing. If you normally don't take the time to do something and you do one day... it doesn't always have to be something grand."
