Sarah Jane's Alien Files

Alien Files is an ongoing 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.

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.

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.
