Kiefer Sutherland has revealed his latest venture into TV has made him appreciate his own family life even more.
The 24 star, who plays the widowed father of a silent 11-year-old boy in new drama Touch, explained: "I have two daughters and two stepsons and I had relatively normal relationships with my children, and we had a very traditional father-daughter, father-son relationship.
"This is the father of a special needs child, who's never been able to verbally communicate with his son, and every day gets up and fights for the most normal relationship he can have."
And although at first glance Sutherland's role in Touch might seem far removed from heroic Jack Bauer in 24, the actor said he admired his character's bravery.
"He's one of the most courageous guys I've ever read about, and that was something that I admired greatly but also moved me as a parent, because it was something that made me realise how fortunate and lucky I was with the relationships I have with my family," he said.
:: Kiefer Sutherland's new TV drama Touch will launch on Sky 1 and Sky 1 HD later this month.
