DEBRA MESSING

The festive film was shot earlier this year (08) in Chicago, Illinois during the city's worst winter in years.

Crew members struggled in the freezing conditions, and Messing could barely stay on her feet.

She says, "It was the worst experience of my entire life.

"We were shooting outside, it was freezing. The director said, 'Go warm up.' I ran in heels and went flying. I don't remember a thing.

"I had 35 X-rays. I ended up being OK, but it was brutal out there."
