Few Doctor Who companions of the program's original run were as controversial as Leela,played by actress Louise Jameson. For one, she was succeeding Elizabeth Sladen's Sarah Jane Smith when she left the show midway through its 16th series. After spending two years in the Royal Shakespeare Company, she was cast as a companion like no other before her for the doctor. Leela, a very complex warrior princess who was extremely intelligent yet lacking in understanding of the ways of much of the material universe, was very much the fourth doctor's Eliza Doolittle. Unfortunately the personalities and Jameson and Tom Baker clashed and she left the program in 1978-recommending Mary Tamm for the role of the new companion Romana. Leela is one of the most unique and fascinating Doctor Who companions and I wish Louise Jameson a very happy birthday today!
