Patrick Dempsey is in final talks to appear in Bridget Jones's Baby. Deadline reports Dempsey wanted to star alongside Renee Zellweger and Colin Firth - who's returning as Mark Darcy - in the much-discussed third installment of the franchise. Plot details of the movie remain a closely-guarded secret, although it's clear from its title that the mishap-prone Brit is unexpectedly expecting a baby. However, it's not yet clear who fathered the child.
