Robert Downey, Jr. has no plans to take time off from movie-making when he becomes a father again next year, insisting he "can't see that happening" in the near future.

The actor's wife, Susan Downey, is pregnant with their first child, a half-sibling for the "Iron Man" star's son, Indio, from his first marriage to actress Deborah Falconer.

The baby is due in February, but with his busy schedule, Downey, 46, admits he'll be a working father for the youngster's early years.

He tells Britain's Live magazine, "It's funny. I used to say that I'd welcome a bullet to the forehead if I ever ended up as a 40-something, remarried, marketable, big-action movie dad living in a cozy cul-de-sac in suburban L.A. Now I am that guy."

"It just goes to show that I usually don't know what's good for me in life. But I'm getting better at knowing that stuff. I don't need to rub against the grain nearly as much as I used to. I'm 46 now, so the countdown to my half-century has begun. I'd have to be completely deranged not to stress about that."

"Life is good. With a new baby on the way, maybe I ought to think about slowing down a little. But I can't see that happening in the short term."
