Schedule an appointment with a professional photographer. Talk to a few photographers and ask to see examples of their work. Select a photographer who specializes in taking headshots. Inform the photographer that the headshot is for a movie extra portfolio. The photograph should capture your natural qualities.
Write a one-page resume. Document your previous experience as a movie extra as well as previous acting experiences. Describe your education, hobbies and interests. In addition to the photograph, the resume may help to catch the casting director's attention. Include your name, email address and telephone number.
Read the portfolio instructions carefully. Pay attention to the guidelines for submitting the portfolio. The details may vary in terms of the size of the photograph, the type of mailing envelope, and how to connect the resume and the photograph. Some directors prefer that the resume be written on the backside of the headshot. Also give special attention to the deadline for submitting the portfolio.
Write a short introductory note. Clip the note to the portfolio. The note may help to set you apart from all the other applicants who are interested in working as a movie interest.
