I interpreted your question a third way, meaning a theater director, in which case you would generally major in theater. Regardless, depending on the classes offered at Spelman and what you mean by "Director," you should choose the major that has classes that would apply most directly to the career you want to pursue and perhaps prepare you for graduate school if you are considering that path.
For example, the theater department may have extensive classes in character development and directing. But the film major may be more focused on the history of film and film criticism. So, even if you want to pursue film direction--because you are already at a specific school--you need to work with their curriculum.
Depending on what is offered, talk to the heads of the departments in the various majors you are considering and get their perspective. If neither major fits precisely what you are looking for, ask an academic advisor about creating an interdisciplinary major to combine two or more fields, so you can take classes in more than one department to create a major that meets your needs. More and more colleges are allowing that these days. Double majors and minors also create alternative solutions when you can't find the exact major you are seeking at a particular school. Good luck!
