Colin Firth On 'Fraught Family Reunion' Of 'Bridget Jones 3'

PRESS ASSOCIATION -- Colin Firth has confirmed the script for Bridget Jones 3 has been written - and joked that filming will be like a "fraught family reunion".

The actor, who played Mark Darcy in Bridget Jones and its sequel Bridget Jones: The Edge Of Reason, said he was looking forward to getting back into the studio with Renee Zellweger, who plays Bridget, and Hugh Grant, who plays caddish Daniel Cleaver.

"It does become a bit of a family at the time, it'll be like one of those rather fraught family reunions at Christmas," he joked.

The sequel is set to centre around Bridget and Mark trying for a baby and failing - only for Bridget to have a fling with Daniel, which apparently leads to her getting pregnant.

Firth revealed: "There's a script. This character has obviously inhabited part of my life, I'm always interested to see where it's taken, and it does look as if it's going somewhere interesting."

Asked if he would wear Mark's famous Christmas jumper to the 'reunion', Colin said: "I wouldn't wear anything else."

Firth can be seen on screen in Tomas Alfredson's adaptation of John Le Carre's book Tinker Tailor Soldier Spy, in cinemas this week.
