The 31-year-old Irish hunk, who welcomed a baby girl in November with wife Amelia Warner, said if the film fails to do well at the box-office then he would change diapers of his daughter, reported Us magazine.
"I'm tired. I'm tired. It's a mad year, professionally, personally. Right now I don't need to work if there's nothing that I want to do. I've done three jobs back to back. Let's see how they are received. If there's nothing I want to do, I'll just play golf and change (diapers)," he said.
"There are a couple of classic knots I know now and I've put them to good use far too many times recently. In fact I'd like to do a job where I don't have to tie women to beds," he added.
