You only have one shot to get a casting director's attention, so the letter you write should be catchy, professional and memorable. If you use informal language or slang, your correspondence may end up in the bin. Give your letter a professional look, both in format and paper quality. Allow your language to sing and you improve your chances of getting an interview or audition.
Type your letter in formal letter style. This includes your address, skipping one line and adding the date, and then skipping a line and inserting the casting director's name and address. Be sure to address the letter to the proper person, not the agency. Miss a line and add the salutation, such as "Dear Mr Smith," followed by a colon and another blank line. Begin your first paragraph, and include a blank line between each paragraph. Each line should be single-spaced and justified to the left. Use a simple font like Times New Roman, Arial or Helvetica in 10 or 12 point size.
Double-check the casting director's name and ensure correct spelling. If you don't make extra effort in this area and misspell her name, the casting director is less likely to trust you to do the work necessary for a film, TV or stage part.
Introduce yourself in the first paragraph with any personal connection you may have. For instance, if you met the casting director's brother at a party who suggested you contact him, write that in your letter.
List no more than three parts in which you have been cast. You may explain that you recently finished a television series pilot and are appearing in a provincial theatre play, for example. If you are cast in a stage play, offer the casting director tickets to see the performance. Ensure you have that authority before you offer the tickets.
Close the letter simply. Thank the casting director for her time and give her a contact number. Miss a line and give the closing, such as "Kind regards," or "Sincerely," and then press the "Return" key four times and type your name. Sign your name in ink in the space where you returned four times, above your typed name.
Keep the letter short, concise and clear. Rambling on about how great you are guarantees your letter will not be finished by the casting director.
