How do I go about getting the actors autographs?
Use a S.A.S.E. - The use of a Self-Addressed Stamped Envelope (S.A.S.E.) is a necessity if you want to receive a response from a celebrity. This is considered one of the basic rules of autograph collecting etiquette, and will GREATLY increase your chances of receiving a reply.
Make It "Short and Sweet" - When writing a letter to a celebrity, it is advisable to write no more than one page. Although celebrities may be thrilled that you appreciate their work, or liked their acting in a certain TV show or movie, they simply do not have enough time to read multi-page letters from fans. Also, when writing to a celebrity or idol, try to include some specific references to their work that you particularly like(d). Be specific. Mention character names that they have played and movies in which they have starred or appeared.
Have Patience - After sending out an autograph request, have patience. Due to their busy schedules, it may take as long as 6 months to 1 year to respond.
