The Constant Gardener star decided to lighten her workload to enjoy quality time with six-year-old Henry, her only child with her ex-partner, director Darren Aronofsky.
She tells USA Today, "I just wanted to be at home, to be with Henry. I need passion if I'm going to work, a lot of passion. That's how I feel right now. It has to be a situation where I have to do it.
"Henry's dad was filming (new movie) Noah, so I didn't want to be filming at the same time. We just do regular stuff. We go to Tompkins Square Park (in New York City). Henry is into scootering on the street... This city is very friendly to children. You just cab it or bus it or tube it. It's just endless excursions."
Weisz is now married to James Bond star Daniel Craig and they live in New York.
