Sarah Jane's Alien Files

Alien Files used to be a series of webisodes created by the BBC for The Sarah Jane Adventures website, which started during its third series. It is similar to the Monster Files. At the start of Series 4, it has since become a half-hour spin-off show featuring more thorough detail of aliens.

The series was presented by Mr. Smith, Sarah Jane Smith's computer, along with one of the children, either Clyde, Rani or both. The children had Mr. Smith access his video vaults to review previous aliens they had encountered. In the first episode of the TV edition, Sarah Jane had Mr Smith publish files of various aliens she encountered so people could no how to stop them when she and her team weren't there.

Canonicity
Unlike the Monster Files, the canonicity of The Alien Files is not uncertain. The only aliens mentioned are those which the children had encountered before and no information contradicted the main series.

Trivia
In the TV edition, as Mr Smith accesses data on aliens. The Arcateenians, Bane, Macra, the Beast, Krillitanes, Lazarus Monster and also the Fairies are seen. However unlike in Revenge of the Slitheen where their whole body is seen rotating, a close-up of their face is seen.

The Mona Lisa Alien File was the only one to read the format of "Alien File: Mona Lisa", where as the others simply read "Androvax Alien File" etc.
