Kirsten Dunst in July. The actor says a family emergency involving her son's health happened when she was filming a movie earlier this year. Kirsten Dunst was filming an upcoming movie in Budapest early this year when she was confronted with a health emergency involving her youngest son.

Dunst's husband Jesse Plemons, 37, and their two sons, Ennis, 7, and James, joined her in January during filming. The family rented a house in Budapest and enrolled their older son in a local school, but when James developed a health problem, the family was sent back to Los Angeles to be around their loved ones.

The actress didn't disclose the specifics but compared it to "'Final Destination,' where you're imagining all the things that could go wrong, worst-case scenarios happening to your child."
