As quoted from Den of Geek:
"Contrary to press reports today we can confirm that no new episodes of The Sarah Jane Adventures will be filmed following the tragic death of actress Elisabeth Sladen in April, 2011. As a tribute to Elisabeth the six episodes that were recorded with her last year will be broadcast on CBBC at a date to be confirmed."
This news brings mixed feelings for this fan-sadness and happiness. Although Sarah Jane will no longer be fighting new aliens and monsters in the distant future, she will be gracing our screens with new adventures for one last time.
Of course, for as long as there are fans remembering, she will never truly disappear from our hearts.
