Doctor Who fans across the globe have had plenty to watch, interact and keep themselves entertained with over the last few weeks of lockdown due to the ongoing COVID-19 pandemic.

There has been countless episode tweet-a-longs featuring the cast and crew sharing their thoughts and behind the scenes info as well as new stories being released including the Rose prequel and sequel to coincide with NuWho’s 15th anniversary.

Former showrunner Russell T Davies, the man behind the revival in 2005 and subsequent spin offs Torchwood and The Sarah Jane Adventures, has revealed another brand-new story.

This new story titled Farewell, Sarah Jane will premiere on Sunday April 19th with the aim to say goodbye to the franchise’s most-beloved companion.

Elisabeth Sladen was a regular cast member from 1973 to 1976, alongside both Jon Pertwee and Tom Baker, and reprised the role many times in subsequent decades, both on Doctor Who and its spin-offs, K-9 and Company and The Sarah Jane Adventures.

The Sarah Jane Adventures was first seen by its original British audience in the form of a 60-minute New Year’s Day special in 2007.

The series went on for a further fifth years until sadly due to the illness of Sladen, and her subsequent death on 19 April 2011, filming for the second half of the fifth series, which was due to air in the autumn of 2011, was postponed and later cancelled.

Filming for three stories of the fifth series had been finished, and thus post-production on these stories was completed. The final series was aired from 3 to 18 October 2011 on CBBC and ended with a tribute to Elisabeth Sladen in the form of a video montage of scenes from the series and Doctor Who.

Farewell, Sarah Jane will be available on the Doctor Who YouTube, Facebook, Twitter & Instagram page from 5PM tomorrow.
