Renee Zellweger suffered from "nostricles" on the set of her new movie

Renee Zellweger suffered from "nostricles" on the set of her new movie.

The 39-year-old actress was so cold while shooting 'New in Town' in Winnipeg, Canada, she often didn't realise when her nose was running, meaning the liquid would freeze.

She said: "My worst moment while making the film was nostricles, which are not sexy. You don't know that your nose is running because you can't feel it. It just freezes before you realise you need a Kleenex. Boy, I tell you, that's funny."

Renee added the weather conditions were so bad when she was making the film - in which she stars as a hard-nosed executive who is called to a tiny community to help the local factory become profitable again, or close it down - it was almost dangerous.

She explained to Parade.com: "It was so cold that you're taking your life into your own hands to go out of the house. So cold that wearing the clothes I did on the set, the little skirts and thin jackets, was really stupid even if it did look funny."
