Series 4 (SJA)

Series 4 of The Sarah Jane Adventures is expected to air on BBC One and CBBC on the 11th October 2010. According to Doctor Who Magazine, pre-production was under way as early as November 2009. On 4 March 2010, the BBC officially announced that production had been commissioned, with filming expected to begin by the end of March. (The same announcement also confirmed that a 5th series for 2011 had also been commissioned.)

The 4th season will see the return of all the core cast members (though the 4 March 2010 announcement did not indicate whether K9 would appear, K9 was seen on set when filming began) for a 12-episode series. The series begins on Monday 11 October, 2010.

For the new series, Brian Minchin joins as producer, with Phil Ford as co-producer. Russell T Davies remains as executive producer along with Nikki Wilson.

 * On-set videos show Luke saying goodbye to Sarah Jane and the rest of the cast, making it likely that he will leave in this series to be replaced by the new character of Series 5. Alexander Armstrong has also said that Luke goes off to university, and that K-9 leaves with him. However, onset videos of Tommy Knight during the series finale suggest he will return.
