Behind the scenes

 * Louise is the only lead female companion created specifically for the movies, though her equivalent in the TV story The Dalek Invasion of Earth would be Barbara Wright.
 * The character was added to the film as a replacement for the movie version of Barbara when Jennie Linden did not return for the second film; this allowed the romantic subplot originally assigned to the older version of Susan in the TV story to proceed.
