Movie bosses behind 2001 comedy Bridget Jones's Diary and its 2004 sequel Bridget Jones: The Edge of Reason began working on a third installment in 2011 but the project hit a number of delays due to problems with the script.
According to Britain's The Sun newspaper, British actress Emma Thompson was drafted in to rework the screenplay, written by David Nicholls and the author of the novels, Helen Fielding, and production is now in the early stages.
Filming reportedly began during an Ed Sheeran concert at Croke Park in Dublin, Ireland last month (Jul15) and Zellweger's body double was spotted sitting on the shoulders of a mystery man.
A source tells the publication, "There was no risk in filming Renee at a busy gig. But they knew the cat would be out the bag the minute people saw her at the show... Renee's body double and the cameramen were in and out of the crowd as quickly as possible... These are the first moments in early filming for the new movie. None of the show's main talent have been involved yet."
The project is provisionally titled Bridget Jones's Baby.
