Although Lethbridge-Stewart never appeared in the revived series, the character is still alive during the Tenth Doctor's tenure. In the spin-off programme "The Sarah Jane Adventures" story "Revenge of the Slitheen", Sarah Jane Smith says to "give love to the Brig". In the Tenth Doctor episode "The Poison Sky", the Doctor mentions that he could use the help of "the Brigadier". He is then told that "Sir Alistair" is "stranded in Peru", indicating that the Brigadier has been knighted by this time. The first film footage from the classic era to appear in the revived era was his photograph displayed in the slow pan across Sarah Jane Smith's attic in the opening scene of "The Sarah Jane Adventures"’ première, "Invasion of the Bane".
