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.

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.
