In 2006 Elisabeth Sladen returned to Doctor Who as Sarah Jane Smith in School Reunion alongside the 10th Doctor (David Tennant). Later that year filming began for Invasion of the Bane, a special hour long opening episode of The Sarah Jane Adventures which originally aired January 1st 2007.
The Sarah Jane Adventures quickly became one of the most popular shows on CBBC picking up record audiences. In 2009 a special episode, From Raxacoricofallapatorius with Love aired as part of Comic Relief on BBC One.
The show has remained closely linked to Doctor Who. Sarah Jane and her adopted son Luke have turned up in Doctor Who a few times, the most recent being the 10th Doctors final story The End of Time. The Doctor has also shown up in The Sarah Jane Adventures, most recently the 11th Doctor (Matt Smith) in Death of the Doctor.
On the 19th April 2011 Elisabeth Sladen sadly passed away from cancer. My Sarah Jane: A Tribute to Elisabeth Sladen aired on CBBC directly after The Impossible Astronaut.
