What a miserable couple of years it's been for companion actors.Former companion actress Janet Fielding is fighting cancer, it has been revealed.
No more details about her condition are known at the moment but Peter Davison, whose Doctor she appeared opposite as Tegan Jovanka, has won the support of other ex-Doctor actors to launch a fund-raising convention - Project Motor Mouth - that aims to "not only raise money for a good cause but also keep Janet's spirits up."
He, along with Colin Baker, Sylvester McCoy, Paul McGann, and David Tennant, are the first guests announced for the event, which will take place on Saturday 19th January 2013 at the Copthorne Hotel Slough-Windsor. All guests will be appearing subject to work commitments.
The profits from the convention will go to Project Motor House, which is seeking to convert a derelict building in Thanet into a mixed-use venue promoting sustainable technology and a place where youngsters can get help with starting their own businesses. Fielding is the project co-ordinator for the organisation as well as its community champion.
