David Tennant is the latest cast member to pay tribute to Elisabeth Sladen, describing her as “extraordinary”.

Elisabeth, loved for her portrayal of Sarah Jane in Doctor Who and The Sarah Jane Adventures, sadly passed away yesterday morning. The Tenth Doctor actor commented: “I just can’t believe that Lis is gone. She seemed invincible. The same woman who enchanted my childhood, enchanted my time on Doctor Who and enchanted generations who have fallen in love with her – just like I did.”

He said: “I feel very honoured to have shared a TARDIS with Sarah Jane Smith, and I feel very lucky to have shared some time with Lis Sladen. She was extraordinary.”

Tom Baker has also updated his official website with his own tribute to the actress.

Sarah Jane dead? No, impossible! Impossible. Only last week I agreed to do six new audio adventures with her for Big Finish Productions.

She can’t be dead. But she is: she died yesterday morning. Cancer. I had no idea she was ill; she was so private, never wanted any fuss, and now, gone. A terrible blow to her friends and a shattering blow for all those fans of the programme whose lives were touched every Saturday evening by her lovely heroic character.

Meanwhile, Colin Baker has tweeted: “Very sad to hear of the death of Lis Sladen. Great sympathy for her husband and daughter. She was too young to be lost to them”.
