Renee Zellweger is very keen on playing the lead role in another Bridget Jones film – as long as she doesn't have to pile on the pounds.

The actress would love to play the character again despite it going against her doctor's orders.

"I had a panic attack with all the specialists talking about how bad this is for you long-term, putting on that much weight in short periods of time," she said. "The health professionals were warning me about not continuing the project any further. (It was) absolutely horrible (losing the weight). The first lap around the track I felt like I had a small toddler attached to my back."

Assuming another film is in the pipeline, Zellweger would like to see Helen Fielding's literary heroine embark on a new adventure in her life. "I would love her to go to LA and have a baby," she said.
