Initially, "Ed Wood" was in development with Columbia, but when Burton decided he wanted to shoot the film in black-and-white, studio head Mark Canton would not agree to it unless Columbia was given a first-look deal. Burton said black-and-white was "right for the material and the movie, and this was a movie that "had" to be in black-and-white". He insisted on total creative control, and so in April 1993, a month before the original start date, Canton put "Ed Wood" into turnaround. The decision sparked interest from Warner Bros., Paramount Pictures and 20th Century Fox in optioning the film rights, but Burton accepted an offer from Walt Disney Studios, who had previously produced "The Nightmare Before Christmas". Similar to "Nightmare", Disney released "Ed Wood" under their Touchstone Pictures banner. With a budget of $18 million, Disney did not feel the film was that much of a risk, and granted Burton total creative autonomy. Burton also refused a salary, and was not paid for his work on "Ed Wood". Principal photography began in August 1993, and lasted 72 days. Despite his previous six-film relationship with Danny Elfman, Burton chose Howard Shore to write the film score. Under the pressure of finishing the score for "Batman Returns", Burton's relationship with Elfman became strained and Burton admitted he and Elfman experienced "creative differences" during "The Nightmare Before Christmas".
