Georgia Tennant to Lead Big Finish Doctor Who Audio Drama Zero Chill

Georgia Tennant will star in a new Big Finish Productions audio drama titled Zero Chill, the company has announced. The casting marks her return to the Doctor Who franchise 18 years after her appearance in the series, according to collider.com.

Big Finish Productions is the producer behind the audio drama, which carries the Doctor Who name. Further details of the production, including a release date, were not included in the announcement.

Tennant's ties to the franchise extend beyond her own appearance. She is married to David Tennant, who played the Tenth Doctor, and is the daughter of Peter Davison, who played the Fifth Doctor.

The announcement arrives while the television series' future is being weighed elsewhere. In 2005, Russell T. Davies returned as Doctor Who showrunner for a first run, and the BBC later put the show out to competitive tender. Davies said the tender decision would come by something like October 10, with production of a new Doctor and companion starting next summer, while Jed Mercurio, through Hat Trick Mercurio, is currently the front-runner to take control of the series, with a 2028 or 2029 return eyed.
