R.K.O. gave
Val Lewton only $150,000 to make the film, resulting in "creative" producing. This forced many of the scenes requiring special effects to be done in shadows which many believe increased the suspense of the film. When studio execs insisted that more footage of the panther be included in the movie, Lewton was able to maintain the budget and the suspense of the film by limiting how many scenes the panther could be visibly seen and told the cinematographer to "keep the panther in the shadows." Thus the panther was only visible in the office and zoo cage.
