Getting in touch with celebrities for their autographs has gotten easier in the Internet age. Numerous databases exist that will provide this information. Some will provide the information at no charge, others operate as a subscription service. The only drawback is that the contact information may be out-of-date. There is no real protection against this, since information changes quickly, but a good service tries to be diligent in keeping current. Another source is movie studios, or celebrity agencies. Many of these businesses handle the fan mail of stars, and will try to comply with any reasonable requests. If you are seeking the actual signature of someone, it is best to send an item to be signed (be sure to enclose an SASE). If you simply request a signed photo, you will probably receive one of a mass produced reproduction, and the value is diminished.
